test(sync): add client-side sync tests for note-related entities

Add comprehensive tests for syncing NoteType, NoteFieldType, Note, and
NoteFieldValue entities in push.test.ts and pull.test.ts. Tests cover:
- Data format conversion between local and server representations
- Applying pulled entities to local IndexedDB
- Pushing pending changes to server
- Updating existing entities during sync
- Syncing all note-related entities together

Also removes unused variable in sync repository.
