feat(db): add ORDER BY to repository SELECT queries

Ensures deterministic ordering for all multi-row SELECT queries:
- deck/note/noteType findByUserId/findByDeckId: order by createdAt
- card findByNoteId: order by isReversed (normal card first)
- note field values: order by noteFieldTypeId
- sync pull queries: order by id

This guarantees consistent UI display and sync results regardless
of PostgreSQL's internal row ordering.
