Phase 7: End-to-End API Testing - Database setup, migrations, and application fixes

- Switched from psycopg2 to asyncpg for async SQLAlchemy support
- Fixed router registration in main.py - removed duplicate prefixes
- Added user_data export to routers/__init__.py
- Refactored decks router to use DeckManager service layer
- Integrated FuzzyCardMatcher into card_router search endpoints
- Made WishlistCreate.card_id optional for proper schema validation
- Set PostgreSQL password and configured scram-sha-256 auth
- Updated alembic.ini to use local PostgreSQL instead of Docker hostname
- Created generic_schemas.py for reusable schema patterns
- Added test_routers.py and test_schema_validation.py test files
- All 6 Alembic migrations applied successfully (37 tables created)
- Application running on port 8000 with all services connected
