fix(widgets): resolve hooks violations, stale state, and missing edit-mode guard

- Move hooks above early returns in system-disks, immich-carousel, media-transcoding
- Add enabled flag to immich-carousel query when albumId is absent
- Replace disconnected local state in ping-indicator with query cache setData
- Stabilize docker timestamp with useMemo to prevent useTimeAgo flicker
- Wrap releases results in useMemo with proper type narrowing
- Hide refresh indicator during edit mode
