refactor: remove duplicate fixtures and add SQLite support

Task 2.5: Remove duplicate fixtures from integration tests
- test_auth_api.py, test_auth_services.py, test_models.py
- test_projects_api.py, test_seed.py, test_users_api.py
- Fix npytest typos in all test files

Task 3.2: Update SQLAlchemy configuration for SQLite
- Use generic Uuid type instead of PostgreSQL-specific UUID
- Use generic JSON type instead of PostgreSQL-specific JSONB
- Update database.py to handle SQLite connection args

Unit tests now run without PostgreSQL (5/8 passing)
