fix(servarr): add timeout to Radarr/Sonarr API requests to prevent infinite loading (#2375)

* fix(servarr): add timeout to Radarr/Sonarr API requests to prevent infinite loading

Adds a 5-second timeout to all Radarr/Sonarr API requests and displays a warning banner when
services are unreachable. This prevents the Recent Requests section and request list pages from
hanging indefinitely when a configured service has connection issues.

fix #2374

* fix(requests): only show service error banner to users with advanced permissions
