Remove the dead location_database_url / poo_database_url fields and the location_sqlite_path / poo_sqlite_path computed properties from Settings; drop them from the config-page payload and from .env.example. Update the test hardcodes (test_config, test_public_ip, test_smtp) and reduce the conftest test_database_urls fixture to the single app DB. The one-time migration script keeps reading legacy URLs from env/CLI, independent of Settings. pytest 95 passed; ruff clean (pre-existing only).
