Fix SQLite autoincrement and test configuration

- Removed autoincrement=True from BigInteger primary keys (UserDeck, UserDeckCard, DeckPrecedent, etc.)
- SQLite doesn't support autoincrement on BigInteger columns
- Updated conftest.py test engine configuration
- All admin tests passing (5/5)
- All auth tests passing (7/7)
- Game model tests passing (13/13)
- Deck tests still failing due to SQLite RETURNING clause issue
