Implement efficient sync for Todoist and Trello APIs

- Add Todoist Sync API v9 support with incremental sync tokens
- Store sync tokens in SQLite for persistence across restarts
- Add field filtering to Trello API calls to reduce payload size
- Update handlers to use incremental sync (merge changes vs full replace)
