UX: improves composer and thread panel (#21210) This pull request is a full overhaul of the chat-composer and contains various improvements to the thread panel. They have been grouped in the same PR as lots of improvements/fixes to the thread panel needed an improved composer. This is meant as a first step. ### New features included in this PR - A resizable side panel - A clear dropzone area for uploads - A simplified design for image uploads, this is only a first step towards more redesign of this area in the future ### Notable fixes in this PR - Correct placeholder in thread panel - Allows to edit the last message of a thread with arrow up - Correctly focus composer when replying to a message - The reply indicator is added instantly in the channel when starting a thread - Prevents a large variety of bug where the composer could bug and prevent sending message or would clear your input while it has content ### Technical notes To achieve this PR, three important changes have been made: - `<ChatComposer>` has been fully rewritten and is now a glimmer component - The chat composer now takes a `ChatMessage` as input which can directly be used in other operations, it simplifies a lot of logic as we are always working a with a `ChatMessage` - `TextareaInteractor` has been created to wrap the existing `TextareaTextManipulation` mixin, it will make future migrations easier and allow us to have a less polluted `<ChatComposer>` Note ".chat-live-pane" has been renamed ".chat-channel" Design for upload dropzone is from @chapoi 2023-04-25 10:23:03 +02:00			`.chat-side-panel-resizer {`
