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.
The `message_bus_channels` given to `MessageBus.last_ids(*message_bus_channels)` is not ordered, as a result the expectation of the tests could fail, this test ensures we check the contain of the input instead of content+order.
This commit adds the initial part of thread indicator improvements:
* Show the reply count, last reply date and excerpt,
and the participants of the thread's avatars and
count of additional participants
* Add a participants component for the thread that
can be reused for the list
* Add a query class to get the thread participants
* Live update the thread indicator more consistently
with the last reply and participant details

In subsequent PRs we will cache the participants since
they do not change often, and improve the thread list
further with participants.
This commit also adds a showPresence boolean (default
true) to ChatUserAvatar, since we don't want to show the
online indicator for thread participants.

Regressed in eec10efc3dfad0d274cadb60e9e45f2a345b2a5d. It means that backend plugin spec failures in CI were not failing the spec suite.
Fixes recent regressions and skips two of them - to be handled next week.

After this change, in order to join a chat channel, a user needs to be in a group with at least “Reply” permission for the category. If the user only has “See” permission, they are able to preview the channel, but not join it or send messages. The auto-join function also follows this new restriction.

Followup to ba11cf47670891681a8cb579c3a4819421111345,
this commit makes it so that none of the chat message
thread data is serialized if threading_enabled is false
for the channel or if enable_experimental_chat_threaded_discussions
is false, there is no need to serialize the data in this
case.
This adds specs to the mentioned serializers to catch regressions
with MessageBus last_ids and to ensure the correct ones are being
returned and passed down to the ChannelSerializer.
Followup to d8ad5c3
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
