feat(debug-info): add storage, docker, GPU health, and auto-update diagnostics

The Debug Info bundle carried no storage-path info, which stalled diagnosis of
relocation issues like #1050 (moved data not seen by the admin). Add the fields
support actually asks for, all best-effort so one failure never blanks the bundle:

- Storage: resolved host storage root (#938), container path, whether
  NOMAD_STORAGE_PATH is set, and the Kiwix library book count (0 books is the
  tell for an empty/wrong-path library).
- Docker Engine version (reporters currently paste it by hand; needed for
  container/updater issues).
- GPU passthrough health (gpuHealth.status + detected gpu.type) for the
  passthrough-lost-after-update class (#755/#878).
- Auto-update status for core/apps/content plus any auto-disabled reason,
  since the auto-update trilogy shipped.

Adds a public DockerService.getHostStorageRoot() wrapper over the existing
#938 resolver.
