* feat: Implement UI for history visibility acknowledgement.
Shows a banner above the message composer whenever a user opens a room
with non-join history visibility, which they can dismiss.
- Whenever a user opens an encrypted room with non-join history
visibility, show them a banner, unless we have already marked it as
dismissed.
- Whenever a user opens an encrypted room with joined history
visibility, we unmark it as dismissed.
