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.

# Updates a thread. The thread_id and channel_id must

|
# match. For now we do not want to allow updating threads if the
|
|
# enable_experimental_chat_threaded_discussions hidden site setting
|
|
# is not turned on, and the channel must specifically have threading
|
|
# enabled.
|
|
#
|
|
# Only the thread title can be updated.

# @example
|

# Chat::UpdateThread.call(thread_id: 88, channel_id: 2, guardian: guardian, title: "Restaurant for Saturday")
