DEBUG: Add extensive logging to diagnose Matrix message leakage

- Added detailed logging to useSessionSharing Matrix listener setup check
- Added critical debug logging to ChatInput before calling useSessionSharing
- Enhanced Matrix room detection logging with timestamps
- This will help identify why regular chats are still receiving Matrix messages

The issue appears to be that regular chat sessions might be getting
initialRoomId values when they shouldn't, causing Matrix listeners
to be set up for non-Matrix chats.
