UX: Use a dropdown for SSL mode for group SMTP ()
Our old group SMTP SSL option was a checkbox,
but this was not ideal because there are actually
3 different ways SSL can be used when sending
SMTP:

* None
* SSL/TLS
* STARTTLS

We got around this before with specific overrides
for Gmail, but it's not flexible enough and now people
want to use other providers. It's best to be clear,
though it is a technical detail. We provide a way
to test the SMTP settings before saving them so there
should be little chance of messing this up.

This commit also converts GroupEmailSettings to a glimmer
component.

FIX: Use login SMTP auth for office365 in group mailer ()
Followup 7b627dc14b

In this other commit, I changed the email settings validator
to always use the `login` authentication method for
office365 and outlook, but I didn't change the actual
group SMTP mailer to do this.

This commit fixes that issue and does some minor refactoring.

FIX: Add higher read & open timeouts for group SMTP emails ()
When sending SMTP for group SMTP functionality, we
are running into timeouts for both read and open
when sending mail occassionally, which can cause issues
like the email only being sent to _some_ of the recipients
or to fail altogether.

The defaults of 5s are too low, so bumping them up to
the defaults of the `net-smtp` gem.

FIX: don't add "Re:" prefix in email subject for first post of group PMs. ()
Previously, it will add a "Re:" prefix to all the emails passing through the group SMTP mailer. It's creating confusion while receiving the mail for the first time on a PM.

SECURITY: BCC active user emails from group SMTP ()
When sending emails out via group SMTP, if we
are sending them to non-staged users we want
to mask those emails with BCC, just so we don't
expose them to anyone we shouldn't. Staged users
are ones that have likely only interacted with
support via email, and will likely include other
people who were CC'd on the original email to the
group.

FEATURE: Log the SMTP response in EmailLog ()
When sending emails with delivery_method_options -> return_response
set to true, the SMTP sending code inside Mail will return the SMTP
response when calling deliver! for mail within the app. This commit
ensures that Email::Sender captures this response if it is returned
and stores it against the EmailLog created for the sent email.

A follow up PR will make this visible within the admin email UI.

FEATURE: Allow sending group SMTP emails with from alias ()
This commit allows group SMTP emails to be sent with a
different from email address that has been set up as an
alias in the email provider. Emails from the alias will
be grouped correctly using Message-IDs in the mail client,
and replies to the alias go into the correct group inbox.

FIX: Do not show recipient user in email participants list ()
This commit removes the recipient's username from the
respond to / participants list that is shown at the bottom
of user notification emails. For example if the recipient's
username was jsmith, and there were participants ljones and
bmiller, we currently show this:

> "reply to this email to respond to jsmith, ljones, bmiller"

or

> "Participants: jsmith, ljones, bmiller"

However this is a bit redundant, as you are not replying to
yourself here if you are the recipient user. So we omit the
recipient user's username from this list, which is only used
in the text of the email and not elsewhere.

FIX: Change email from to not have via site_name for group SMTP ()

FIX: Do not show In Reply To for group SMTP emails ()
We do not want to show the In Reply To section of the
group SMTP email template, it is similar to Context Posts
which we removed and is unnecessary.

This PR also removes the link to staged user profiles in
the email; their email addresses will just be converted
to regular mailto: links.

FIX: Improve participant display in group SMTP emails ()
This PR makes several changes to the group SMTP email contents to make it look more like a support inbox message.

* Remove the context posts, they only add clutter to the email and replies
* Display email addresses of staged users instead of odd generated usernames
* Add a "please reply above this line" message to sent emails

FEATURE: Use group SMTP job and mailer instead of UserNotifications change ()
This PR backtracks a fair bit on this one https://github.com/discourse/discourse/pull/13220/files.

Instead of sending the group SMTP email for each user via `UserNotifications`, we are changing to send only one email with the existing `Jobs::GroupSmtpEmail` job and `GroupSmtpMailer`. We are changing this job and mailer along with `PostAlerter` to make the first topic allowed user the `to_address` for the email and any other `topic_allowed_users` to be the CC address on the email. This is to cut down on emails sent via SMTP, which is subject to daily limits from providers such as Gmail. We log these details in the `EmailLog` table now.

In addition to this, we have changed `PostAlerter` to no longer rely on incoming email email addresses for sending the `GroupSmtpEmail` job. This was unreliable as a user's email could have changed in the meantime. Also it was a little overcomplicated to use the incoming email records -- it is far simpler to reason about to just use topic allowed users.

This also adds a fix to include cc_addresses in the EmailLog.addressed_to_user scope.

FEATURE: Use group SMTP settings for sending user notification emails (initial) ()
This PR changes the `UserNotification` class to send outbound `user_private_message` using the group's SMTP settings, but only if:

* The first allowed_group on the topic has SMTP configured and enabled
* SiteSetting.enable_smtp is true
* The group does not have IMAP enabled, if this is enabled the `GroupSMTPMailer` handles things

The email is sent using the group's `email_username` as both the `from` and `reply-to` address, so when the user replies from their email it will go through the group's SMTP inbox, which needs to have email forwarding set up to send the message on to a location (such as a hosted site email address like meta@discoursemail.com) where it can be POSTed into discourse's handle_mail route.

Also includes a fix to `EmailReceiver#group_incoming_emails_regex` to include the `group.email_username` so the group does not get a staged user created and invited to the topic (which was a problem for IMAP), as well as updating `Group.find_by_email` to find using the `email_username` as well for inbound emails with that as the TO address.

#### Note

This is safe to merge without impacting anyone seriously. If people had SMTP enabled for a group they would have IMAP enabled too currently, and that is a very small amount of users because IMAP is an alpha product, and also because the UserNotification change has a guard to make sure it is not used if IMAP is enabled for the group. The existing IMAP tests work, and I tested this functionality by manually POSTing replies to the SMTP address into my local discourse.

There will probably be more work needed on this, but it needs to be tested further in a real hosted environment to continue.

FEATURE: Improve group email settings UI ()
This overhauls the user interface for the group email settings management, aiming to make it a lot easier to test the settings entered and confirm they are correct before proceeding. We do this by forcing the user to test the settings before they can be saved to the database. It also includes some quality of life improvements around setting up IMAP and SMTP for our first supported provider, GMail. This PR does not remove the old group email config, that will come in a subsequent PR. This is related to https://meta.discourse.org/t/imap-support-for-group-inboxes/160588 so read that if you would like more backstory.

### UI

Both site settings of `enable_imap` and `enable_smtp` must be true to test this. You must enable SMTP first to enable IMAP.

You can prefill the SMTP settings with GMail configuration. To proceed with saving these settings you must test them, which is handled by the EmailSettingsValidator.

If there is an issue with the configuration or credentials a meaningful error message should be shown.

IMAP settings must also be validated when IMAP is enabled, before saving.

When saving IMAP, we fetch the mailboxes for that account and populate them. This mailbox must be selected and saved for IMAP to work (the feature acts as though it is disabled until the mailbox is selected and saved):

### Database & Backend

This adds several columns to the Groups table. The purpose of this change is to make it much more explicit that SMTP/IMAP is enabled for a group, rather than relying on settings not being null. Also included is an UPDATE query to backfill these columns. These columns are automatically filled when updating the group.

For GMail, we now filter the mailboxes returned. This is so users cannot use a mailbox like Sent or Trash for syncing, which would generally be disastrous.

There is a new group endpoint for testing email settings. This may be useful in the future for other places in our UI, at which point it can be extracted to a more generic endpoint or module to be included.

FIX: Ensure group SMTP and message builder always uses from address for Reply-To when IMAP is enabled ()
There is a site setting reply_by_email_enabled which when combined with reply_by_email_address creates a Reply-To header in emails in the format "test+%{reply_key}@test.com" along with a PostReplyKey record, so when replying Discourse knows where to route the reply.

However this conflicts with the IMAP implementation. Since we are sending the email for a group via SMTP and from their actual email account, we want all replys to go to that email account as well so the IMAP sync job can pick them up and put them in the correct place. So if the group has IMAP enabled and configured, then the reply-to header will be correct.

This PR also makes a further fix to 64b0b50 by using the correct recipient user for the PostReplyKey record. If the post user is used we encounter this error:

if destination.user_id != user.id && !forwarded_reply_key?(destination, user)
  raise ReplyUserNotMatchingError, "post_reply_key.user_id => #{destination.user_id.inspect}, user.id => #{user.id.inspect}"
end
This is because the user above is found from the from_address, but the destination which is the PostReplyKey is made by the post.user, which will be different people.

FEATURE: Allow email image embed with secure media ()
This PR introduces a few important changes to secure media redaction in emails. First of all, two new site settings have been introduced:

* `secure_media_allow_embed_images_in_emails`: If enabled we will embed secure images in emails instead of redacting them.
* `secure_media_max_email_embed_image_size_kb`: The cap to the size of the secure image we will embed, defaulting to 1mb, so the email does not become too big. Max is 10mb. Works in tandem with `email_total_attachment_size_limit_kb`.

`Email::Sender` will now attach images to the email based on these settings. The sender will also call `inline_secure_images` in `Email::Styles` after secure media is redacted and attachments are added to replace redaction messages with attached images. I went with attachment and `cid` URLs because base64 image support is _still_ flaky in email clients.

All redaction of secure media is now handled in `Email::Styles` and calls out to `PrettyText.strip_secure_media` to do the actual stripping and replacing with placeholders. `app/mailers/group_smtp_mailer.rb` and `app/mailers/user_notifications.rb` no longer do any stripping because they are earlier in the pipeline than `Email::Styles`.

Finally the redaction notice has been restyled and includes a link to the media that the user can click, which will show it to them if they have the necessary permissions.

PERF: Replace video and audio links in search blurb while indexing.
In the near future, we will be swtiching to PG headlines to generate the
search blurb. As such, we need to replace audio and video links in the
raw data used for headline generation. This also means that we avoid
replacing links each time we need to generate the blurb.
