feat(web): adminRequests cache key + staleTime polish

- qk.adminRequests defaults to status='all' when no filter is set; the unfiltered
  endpoint returns every status, so caching it as 'pending' was a latent mismatch.
- 60s staleTime on lidarrConfig + myRequests — both are session-stable enough
  that refetching on every consumer-page mount produced needless flicker.
