Add queue listing and removal/blocklisting to the shared arr client.
The Downloads view now fetches SABnzbd and both arr queues in parallel,
shows status, progress and import problems, flags items needing
attention in the summary, and supports removing or blocklisting items.

SABnzbd client (queue, history, pause/resume, delete, retry) with lenient
number decoding and API-key-safe errors. Downloads view polls while
visible, shows queue and history, and supports pause, delete (with
confirmation) and retry. Add dev/ with pinned Radarr/Sonarr/SABnzbd
containers wired together for manual testing.
