Maurice 7298285a43 refactor(collab): share the chat logic between desktop and phone
collabModel moves from the phone tabs into components/Collab so both
shells read it, and the desktop chat drops its own copies of the time,
date separator and emoji only helpers for the model's.

useCollabChatData holds the messages, paging, live updates, the draft with
its images, and sending, deleting and reacting. The desktop hook keeps its
emoji picker, hover and delete animation, the phone tab its long press
popover; where they differed (older page errors, scrolling after a remote
delete, upload progress, the edit permission on send) the hook takes an
option.
