kikootwo 789a2e50ef Add sourceHeaders and conditional OIDC groups
Add support for passing sourceHeaders when fetching NZB/torrent files: extend AddDownloadOptions and SABnzbd AddNZBOptions, forward headers in sabnzbd and nzbget clients, and populate sourceHeaders in download-torrent.processor (injecting Prowlarr API key as X-Api-Key for proxy URLs). Make OIDC request scope conditional: only include the 'groups' scope when group-based access control or admin-claim is enabled (update provider logic, add tests, and update setup UI text). Also remove explicit take:100 in Plex processors and add CLAUDE guidance about requesting approval before implementing code changes.
