Set stats query staleTime to 0 with refetchOnMount always, and unmount
inactive file admin tabs so returning to the stats view triggers a new fetch
instead of serving the 30s React Query cache.
Remove w_uploads.storage_driver and route all read/write/delete paths through
storage.Active() backed by storage_config.driver. Block direct driver switches
when uploads exist; require migration task instead. Simplify migration to
cursor-based file_path iteration without per-row driver updates.
Saving storage settings now activates the selected driver immediately
instead of staging it until migration. When the driver changes, existing
upload rows are repointed to the new storage_driver so /f/{id} reads use
the correct backend. ForDriver can also open non-active drivers from the
saved multi-backend config.
When switching storage drivers in admin settings, save now validates
connectivity against the selected target backend instead of retesting
the still-active driver. The active driver remains unchanged until
migration completes, so unreachable MinIO no longer blocks saving local
storage settings.
Move route-specific admin components from components/common/admin into
app/(main)/admin/<feature>/components/. Split AdminService god object into
domain services, fix UploadService to use BaseService, add AdminUploadService,
consolidate DB export into DbManageService, and migrate consumers to the
unified services entry.
