feat: add comprehensive logging to settings service

- Add debug logs for settings loading from nostr
- Log when settings are found, missing, or timeout
- Add logging for settings save operations
- Track settings event publishing to relays

This will help diagnose why custom fonts/settings aren't being applied.
