fix(nav): add qBittorrent to per-service-type navbar entries

qBittorrent was missing from SERVICE_TYPE_NAV_ENTRIES, so configured qBit
instances never appeared in the left nav (unlike jellyfin/prometheus/etc.).
Add entry with Magnet icon. navEntries.test.ts filters by configured types
(no fixed-count assertion) so it stays green.
