Update sql_routes to use SQLAlchemy session

[nishu-builder]

Summary

• Updated sql_routes.py to use db_session() and text() instead of MettaRepo
• Removed MettaRepo dependency from server.py entirely
• create_app() no longer requires any parameters

This completes the migration of app_backend from raw SQL to SQLAlchemy. The MettaRepo class now only contains connection pool infrastructure and migration code - all domain query methods have been moved to the new queries/ modules.
