Compatibilité Sonarr : flux RSS Torznab, catégories qBittorrent, save_path, TLS auto-signé

- torznab : tvsearch sans q sert les nouveautés (RSS sync + test Sonarr)
  au lieu d'une erreur 400 — ajoute TorznabService.latest_releases()
- qbit : POST /torrents/createCategory + GET /torrents/categories stateful
  (Sonarr crée sa catégorie tv-sonarr puis la revérifie)
- qbit : /app/preferences expose save_path=/downloads (health Sonarr)
- sonarr : verify=False sur httpx — reverse proxy swizzin en certificat
  auto-signé (usage LAN)
