DEV: Migrate Chat::MessageCreator to a service (#22390)
Currently, the logic for creating a new chat message is scattered
between a controller and an “old” service.

This patch address this issue by creating a new service (using the “new”
sevice object system) encapsulating all the necessary logic.
(authorization, publishing events, etc.)

FEATURE: thread pagination (#22624)
Prior to this commit we were loading a large number of thread messages without any pagination. This commit attempts to fix this and also improves the following points:

- code sharing between channels and threads:
Attempts to reuse/share the code use in channels for threads. To make it possible part of this code has been extracted in dedicated helpers or has been improved to reduce the duplication needed.

Examples of extracted helpers:
- `stackingContextFix`: the ios hack for rendering bug when momentum scrolling is interrupted
- `scrollListToMessage`, `scrollListToTop`, `scrollListToBottom`:  a series of helper to correctly scroll to a specific position in the list of messages

- better general performance of listing messages:
One of the main changes which has been made is to remove the computation of visible message during scroll, it will only happen when needed (update last read for example). This constant recomputation of `message.visible` on intersection observer event while scrolling was consuming a lot of CPU time.

FEATURE: new jump to channel menu (#22383)
This commit replaces two existing screens:
- draft
- channel selection modal

Main features compared to existing solutions
- features are now combined, meaning you can for example create multi users DM
- it will show users with chat disabled
- it shows unread state
- hopefully a better look/feel
- lots of small details and fixes...

Other noticeable fixes
- starting a DM with a user, even from the user card and clicking <kbd>Chat</kbd> will not show a green dot for the target user (or even the channel) until a message is actually sent
- it should almost never do a full page reload anymore

DEV: Refactor DM channel creation into new service pattern (#22144)
This will be used when we move the channel creation for DMs
to happen when we first send a message in a DM channel to avoid
a double-request. For now we can just have a new API endpoint
for creating this that the existing frontend code can use,
that uses the new service pattern.

This also uses the new policy pattern for services where the policy
can be defined in a class so a more dynamic reason for the policy
failing can be sent to the controller.

DEV: Cleanup unused chat route (#22231)
The `chat/chat#update_user_last_read` route no longer has corresponding
controller action so we should remove it.

FEATURE: Export chat messages to CSV file (#22113)
To export chat messages, go to `/admin/plugins/chat` and click the Create export 
button in the _Export chat messages_ section. You'll receive a direct message 
when the export is finished.

Currently, this exports all messages from the last 6 months, but not more than 
10000 messages.

This exports all chat messages, including messages from private channels and 
users' direct conversations. This also exports messages that were deleted.

FEATURE: Allow users to manually track threads without replying (#22100)
This commit adds a tracking dropdown to each individual thread, similar to topics,
that allows the user to change the notification level for a thread manually. Previously
the user had to reply to a thread to track it and see unread indicators.

Since the user can now manually track threads, the thread index has also been changed
to only show threads that the user is a member of, rather than threads that they had sent
messages in.

Unread indicators also respect the notification level -- Normal level thread tracking
will not show unread indicators in the UI when new messages are sent in the thread.

FEATURE: Custom content summarization strategies. (#21813)
* FEATURE: Content custom summarization strategies.

This PR establishes a pattern for plugins to register alternative ways of summarizing content by extending a class that defines an interface.

Core controls which strategy we'll use and who has access to it through the `summarization_strategy` and `custom_summarization_allowed_groups`. It also defines the UI for summarizing topics.

Other plugins can access this summarization mechanism and implement their features, removing cross-plugin customizations, as it currently happens between chat and the discourse-ai plugin.

* Group membership validation and rate limiting

* Work with objects instead of classes

* Port summarization feature from discourse-ai to chat

* Rename available summaries to 'Top Replies' and 'Summary'

DEV: Remove old ChatController routes for messages & lookup (#21723)
Since 5cce829 and the new
channel view builder, we have no need of these obsolete
routes which have way too much logic in the controller, which
has been superseded by the view builder anyway.

Remove the routes and update the channel message loading to use it.

FEATURE: Thread list initial UI (#21412)
This commit adds an initial thread list UI. There are several limitations
with this that will be addressed in future PRs:

* There is no MessageBus reactivity, so e.g. if someone edits the original
   message of the thread it will not be reflected in the list. However if
   the thread title is updated the original message indicator will be updated.
* There is no unread functionality for threads in the list, if new messages
   come into the thread there is no indicator in the UI.
* There is no unread indicator on the actual button to open the thread list.
* No pagination.

In saying that, this is the functionality so far:

* We show a list of the 50 threads that the user has most recently participated
   in (i.e. sent a message) for the channel in descending order.
* Each thread we show a rich excerpt, the title, and the user who is the OM creator.
* The title is editable by staff and by the OM creator.
* Thread indicators show a title. We also replace emojis in the titles.
* Thread list works in the drawer/mobile.

FIX: Thread mention read state and notification links (#21385)
* FIX: Link to thread for mentions inside thread

When mentioning a user in a thread, when we send the
notification and display it in the UI we want the URL
of the notification to point to the thread URL to open
the panel, rather than the main channel which is confusing.

For now, we don't have a way to highlight the linked-to message
in the thread, we can revisit this later.

* FIX: Mark mention notifications read when thread opens

Since we have no scrolling/message visibility/thread membership
for now, when a user opens the thread panel we just want to mark
all mention notifications relating to messages in the thread
for the user as read.

FEATURE: Reintroduce better thread reply counter cache (#21197)
This was reverted in 38cebd3ed5.
The issue was that I was using Discourse.redis.delete_prefixed
which does a slow redis KEYS lookup, which is not advised in
production. This commit removes that, and also ensures the periodical
thread count update only happens if threading is enabled.

I changed to use a redis INCR/DECR for reply count
cache. This avoids a round trip to redis to GET the current
count, and also avoids multi-process issues, where
if there's two processes trying to increment at the
same time, they may both receive the same value, add one
to it, then both write the same value back.
Then, it's only n+1 instead of n+2.

This also prevents almost all chat scheduled jobs from
running if chat is disabled, the only one remaining is
the message retention job.

Revert "FEATURE: Better thread reply counter cache (#21108)" (#21192)
This reverts commit 180e3e11d1.

Per internal discussions, this is a temporary revert, to investigate if this is causing a performance regression.

FEATURE: Better thread reply counter cache (#21108)
This commit introduces a redis cache over the top of the thread
replies_count DB cache, so that we can quickly and accurately
increment/decrement the reply count for all users and not have
to constantly update the database-level count. This is done so
the UI can have a count that is displayed to the users on each
thread indicator, that appears to live update on each chat
message create/trash/recover inside the thread.

This commit also introduces the `Chat::RestoreMessage` service
and moves the restore endpoint into the `Api::ChannelMessages`
controller as part of incremental migrations to move things out
of ChatController.

Finally, this commit refactors `Chat::Publisher` to be less repetitive
with its `MessageBus` sending code.

FIX: Trashing message should reset last read (#20912)
When a chat message is trashed and the message is used
for someone's UserChatChannelMembership#last_read_message_id,
the user would end up with some read state issues until
someone posted a new message in the channel, since we didn't
clear it like we did on bulk message delete.

This commit fixes the issue, and also takes the opportunity
to start a MessagesController in the API namespace, and move
the trash message functionality into the new service format.

FEATURE: Mark all chat channels read with a shortcut (#20629)
This commit adds a keyboard shortcut (Shift+ESC) for chat which marks all
of the chat channels that the user is currently a following member of as read,
updating their `last_read_message_id`. This is done via a new service.

It also includes some refactors and controller changes:

* The old mark message read route from `ChatController` is now supplanted
  by the `Chat::Api::ReadsController#update` route.
* The new controller can handle either marking a single or all messages read,
  and uses the correct service based on the route and params.
* The `UpdateUserLastRead` service is now used (it wasn't before), and has been slightly
  updated to just use the guardian user ID.

DEV: properly namespace chat (#20690)
This commit main goal was to comply with Zeitwerk and properly rely on autoloading. To achieve this, most resources have been namespaced under the `Chat` module.

- Given all models are now namespaced with `Chat::` and would change the stored types in DB when using polymorphism or STI (single table inheritance), this commit uses various Rails methods to ensure proper class is loaded and the stored name in DB is unchanged, eg: `Chat::Message` model will be stored as `"ChatMessage"`, and `"ChatMessage"` will correctly load `Chat::Message` model.
- Jobs are now using constants only, eg: `Jobs::Chat::Foo` and should only be enqueued this way

Notes:
- This commit also used this opportunity to limit the number of registered css files in plugin.rb
- `discourse_dev` support has been removed within this commit and will be reintroduced later
