Slice 1 of jellyfin-service-registry. Jellyfin is configured exclusively via the service registry now; the machine-level media_root/path_prefix fields were dead duplicates of the global config. - services/settings_store.py: DEFAULT_SERVICES no longer includes "jellyfin" (now ["monitoring", "files"]). Removed machine-level media_root/path_prefix from _default_local_machine, _row_to_machine, _normalize_machine_payload, _seed_local_machine, get_machine_config, and upsert_machine. _default_local_machine no longer reads global config, so the get_settings import is dropped. - routers/settings.py: removed media_root/path_prefix from MonitoringMachineInput (dead API input; store already ignored them). The global config remote_media_root/path_prefix properties + path_utils.py are unchanged (files.py and media_index still use them for Jellyfin->SSH path resolution). ruff clean; 239 backend tests pass.
