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.
This commit implements all the necessary logic to create thread seamlessly. For this it relies on the same logic used for messages and generates a `staged-id`(using the format: `staged-thread-CHANNEL_ID-MESSAGE_ID` which is used to re-conciliate state client sides once the thread has been persisted on the backend.
Part of this change the client side is now always using real thread and channel objects instead of sometimes relying on a flat `threadId` or `channelId`.
This PR also brings three UX changes:
- thread starts from top
- number of buttons on message actions is dependent of the width of the enclosing container
- <kbd>shift + ArrowUp</kbd> will reply to the last message
We currently don't have a nice UI to show unread messages for the thread,
and it will take some time to create one. For now, this commit makes it so
new messages inside a thread do not count towards a chat channel's unread
counts, and new messages sent in a thread do not update a user's `last_read_message_id`
for a channel.
In addition, this PR refactors the `Chat::ChannelFetcher` to use the `Chat::ChannelUnreadsQuery`
query class for consistency, and made said class able to return zeroed-out records
for channels the user is not a member of.
Finally, a small bug is fixed here where if a user's `last_read_message_id` for
a channel was a thread's OM ID, then the thread OM would not show in the
main channel stream for them until another reply to the channel was posted.
This commit introduces a new thread indicator for channels with `threading_enabled`
set to true and the `enable_exp` site setting set to true. In addition, in the main channel
stream we now hide all messages that are linked to threads except for the original message,
disabling the concept of an "echo mode" for now, we may revisit this in future. We also
remove the jigsaw puzzle "Open Thread" button for message actions, since the thread
indicator can just be used instead.
This also stops the `Chat::Publisher` from sending any messages related to chat
messages that are linked to a thread, unless that chat message is the OM of the
thread. A subsequent PR will link up all MessageBus events within the thread panel,
and for the message indicators.
Another subsequent PR will add the excerpt of the latest message in each thread,
as well as the avatars of the users messaging in the thread.
