When loading posts in a topic, the topic level guardian
checks are run multiple times even though all the posts belong to the
same topic. Profiling in production revealed that this accounted for a
significant amount of request time for a user that is not staff or anon.
Therefore, we're optimizing this by adding memoizing the topic level
calls in `PostGuardian`. Speficifally, the result of
`TopicGuardian#can_see_topic?` and `PostGuardian#can_create_post?`
method calls are memoized per topic.
Locally profiling shows a significant improvement for normal users
loading a topic with 100 posts.

# Context
When a topic is reviewable by a group we give those group moderators some admin abilities including the ability to delete a topic.
# Problem
There are two main problems:
1. Currently when a group moderator deletes a topic they are redirected to root (not the same for staff)
2. Viewing the categories deleted topics (`c/foo/1/?status=deleted`) does not display the deleted topic to the group moderator (not the same for staff).
# Fix
If the `deleted_by` user is part a group that matches the `reviewable_by_group` on a topic then don't redirect. This is the default interaction for staff to give them the ability to do things like restore the topic in case it was accidentally deleted.
To render the deleted topics as expected for the group moderator I am utilizing [the guardian scope of `guardian.can_see_deleted_topics?` for said category](https://github.com/discourse/discourse/pull/19618/files#diff-288e61b8bacdb29d9c2e05b42da6837b0036dcf1867332d977ca7c5e74a44297R802-R803)
We show live user status on mentions starting from a76d864. But status didn’t appear on the post that appears on the bottom of the topic just after a user posted it (status appeared only after page reloading). This adds status to just posted posts.
We need to set the local state of a channel before performing any async operations. Otherwise, multiple leave/join calls can race against each other and cause the local state to get out-of-sync with the server.

Instead of relying on the `ILIKE` operator to filter out image links, we
can instead rely on the `TopicLink#extension` column which allows us to
more efficiently filter out image links.
This optimization mainly affects topics that are link heavy which is
common in topics with alot of replies. When profiling a production
instance for a topic with 10K replies and 2.5K `topic_links`, this
optimization reduces the query time from ~18ms to around ~4ms.
Group names will be used as CSS classes in some components while rendering the public HTML output. It will happen when a group is set as the default primary for users. Or when a group has either a flair icon or flair upload. So we should warn the admins when they restrict the group's visibility level.

Autocomplete with fadeout was not scrolling on arrow
key press in chat, since the input is treated slightly
differently. We just need to find the fadeout div sooner.

The way our markdown raw_html hoisting worked, we only
supported one level of hoisting the HTML content. However
when nesting [chat] transcript BBCode we need to allow
for multiple levels of it. This commit changes opts.discourse.hoisted
to be more constant, and the GUID keys that have the hoisted
content are only deleted by unhoistForCooked rather than
the cook function itself, which prematurely deletes them
when they are needed further down the line.
Featured topics are eventually serialized by `ListableTopicSerializer`
which calls `Topic#image_url` which requires us to preload
`Topic#topic_thumbnails`.
Previously, calling `sign_in` would cause the browser to be redirected to `/`, and would cause the Ember app to boot. We would then call `visit()`, causing the app to boot for a second time.
This commit adds a `redirect=false` option to the `/session/username/become` route. This avoids the unnecessary boot of the app, and leads to significantly faster system spec run times.
In local testing, this takes the full system-spec suite for chat from ~6min to ~4min.

only the hashtag autocomplete has a fadeout scroll, so
we still need to scroll on the original div in some
cases (e.g. mentions)
Note this is a very large PR, and some of it could have been splited, but keeping it one chunk made it to merge conflicts and to revert if necessary. Actual new code logic is also not that much, as most of the changes are removing js tests, adding system specs or moving things around.
To make it possible this commit is doing the following changes:
- converting (and adding new) existing js acceptances tests into system tests. This change was necessary to ensure as little regressions as possible while changing paradigm
- moving away from store. Using glimmer and tracked properties requires to have class objects everywhere and as a result works well with models. However store/adapters are suffering from many bugs and limitations. As a workaround the `chat-api` and `chat-channels-manager` are an answer to this problem by encapsulating backend calls and frontend storage logic; while still using js models.
- dropping `appEvents` as much as possible. Using tracked properties and a better local storage of channel models, allows to be much more reactive and doesn’t require arbitrary manual updates everywhere in the app.
- while working on replacing store, the existing work of a chat api (backend) has been continued to support more cases.
- removing code from the `chat` service to separate concerns, `chat-subscriptions-manager` and `chat-channels-manager`, being the largest examples of where the code has been rewritten/moved.
Future wok:
- improve behavior when closing/deleting a channel, it's already slightly buggy on live, it's rare enough that it's not a big issue, but should be improved
- improve page objects used in chat
- move more endpoints to the API
- finish temporarily skipped tests
- extract more code from the `chat` service
- use glimmer for `chat-messages`
- separate concerns in `chat-live-pane`
- eventually add js tests for `chat-api`, `chat-channels-manager` and `chat-subscriptions-manager`, they are indirectly heavy tested through system tests but it would be nice to at least test the public API

Follow-up to 8db1f1892d,
this makes the hashtag autocomplete scrolling with arrow
keys work with the new fadeout element that is now used
for the scroll container.
We were using the `for_input: true` param when calling
DiscourseTagging, which is really meant for selecting tags
in the UI, which often need a parent tag selected first
before the child tags in tag group will show. We just
want to show all tags regardless of grouping in hashtag
search.`
We generally do not return muted child categories to the user
if they have muted the parent category, this commit respects that
rule for CategoryHashtagDataSource

* DEV: Skip push notifications for active online users
Currently, users with active push subscriptions get push notifications
regardless of their "presence" on the site.
This change introduces a `push_notification_time_window_mins`
site setting which is used in conjunction with a user's `last_seen_at` to
determine if push notifications should be sent. A user is considered to
be actively online if their `last_seen_at` is within `push_notification_time_window_mins`
minutes. `push_notification_time_window_mins` is set to 10 by default.
