feat(database): add DATABASE_CONFIG_FILE env override
Allow overriding default database.yaml paths via DATABASE_CONFIG_FILE environment variable. When set, uses single specified file instead of default ["database.yaml", "/vault/secrets/database.yaml"] search paths. Maintains backward compatibility when env var not set.
