feat(settings): unify Local network + Companion server URLs via the resolver

- Local network LAN URL -> ServerUrlField + jellyfinProbe (picks http on LAN, confirms it's the Jellyfin server).

- Companion pairing: resolve the server field on blur (jellyfinProbe) + status line, keeping the existing form styling (hook, not the block field).
