UX: makes avatar non interactive in thread participants list (#23847)

It was slightly surprising to have a user card show when click on a thread item list.

More over this commit does:
- moves chat/user-avatar to chat-user-avatar and converts it to gjs
- moves chat/thread/participants to chat-thread-participants
- rewrite the `toggleCheckIfPossible` modifier to only be applied when selecting messages, it prevents the click event to collide with the click of avatars in regular messages
