Subject: feat(server): add Deck CRUD endpoints with tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement complete Deck management API:
- GET /api/decks - List user's decks
- POST /api/decks - Create new deck
- GET /api/decks/:id - Get deck by ID
- PUT /api/decks/:id - Update deck
- DELETE /api/decks/:id - Soft delete deck

All endpoints require authentication and scope data to the
authenticated user. Includes 22 unit tests covering success
and error cases.
