feat(sync): add sync support for note-related entities

Extend the sync system to handle NoteType, NoteFieldType, Note, and
NoteFieldValue entities. This includes:

- Server sync repository and routes for push/pull of new entities
- Client sync queue, push, pull, and conflict resolution for notes
- Update Card sync to include noteId and isReversed fields
- Add comprehensive tests for all sync functionality
