Fix get_optional_database_session to handle uninitialized database

- Moved RuntimeError catch to encompass get_db_session() call
- Previously only caught during import, not during execution
- Now properly yields None when database not initialized
- Fixes test_add_series_endpoint_authenticated test failure
