fix(companion): guarantee dual-path peering — LAN p2p + public anchor, always

The whole point of FIPS: the phone peers with the node's npub using the
LAN endpoint as a direct p2p dial hint AND rendezvouses via a public
anchor when away — neither LAN nor 5G location may matter. The anchor
half only existed when the scanned QR carried fanchors, so pairing
against an older node left the phone LAN-only and everything died on 5G.

The Archipelago vps2 anchor (npub + 146.59.87.168:8444/tcp, lockstep
with core fips/anchors.rs) is now baked into upsertNodePeer as a
guaranteed peer. Mesh connect retry window widened so a first-ever
pairing survives the VPN consent dialog. Served APK: 0.5.3 (vc23).
