Messages to a federated peer that is out of LoRa range (e.g. on another
continent) were dropped into the radio with no fallback, or hung on a dead
FIPS path before reaching Tor — so they never arrived.
- Route a radio contact over the federation transport (FIPS->Tor) when it is
the same node as a federated peer (known archipelago identity -> onion) AND
it is not currently reachable over the radio. Reachable radio peers stay on
the mesh (preferred); oversized/file envelopes still always take federation.
- Resolve the onion via the archipelago identity key (arch_pubkey_hex), not
the firmware routing key, so a radio contact maps to its nodes.json onion.
- Add .fips_timeout(8s) to the federation message POST so an unreachable FIPS
overlay fast-fails to Tor (~3-5s) instead of burning the 120s budget.
