fix(api): synchronize data route with RemoteConfig model rename

Replaces all occurrences of 'AppConfig' with 'RemoteConfig' and 'app_config' with 'remote_config' in the generic data collection route handler (/api/v1/data).

This change aligns the route's logic with the recent model refactoring where the AppConfig model was renamed to RemoteConfig, resolving multiple type errors.
