Make database engine creation SQLite-aware

The new persistence layer unconditionally passes connect_args={"check_same_thread": False} when creating the SQLAlchemy engine. That option is only valid for SQLite drivers; if DATABASE_URL points to PostgreSQL or another backend (which the SaaS‑ready architecture is supposed to support), SQLAlchemy will raise TypeError: Invalid argument(s) 'check_same_thread' sent to create_engine and the app fails during import. Wrap the argument so it is only supplied when the URL uses SQLite, otherwise omit it.
