Peering a node was not enough to message it — you had to be in radio
range once before chat worked, which defeats the point of federating.
`send_message` chose its transport from the attached radio:
let use_typed_envelope =
archy && matches!(device_type, Meshcore | Reticulum);
Only the typed path knows about FIPS/Tor. Everything else fell through to
`peer_dest_prefix`, which resolves an over-the-air ROUTING key — so on a
node running Meshtastic, or with no radio at all, sending to a federated
peer failed. It only worked once a LoRa advert had created a radio twin
for the same archipelago identity, which is precisely the "connect on
LoRa first" the operator hit.
Federation contacts are reachable off-radio by definition — that is what
`upsert_federation_peer` records with `reachable: true` — so the
transport choice must not depend on which radio is plugged in. A
federation-synthetic contact id now always takes the typed path.
This loses no radio-first behaviour: `send_typed_wire` already prefers a
REACHABLE radio twin when the payload fits the frame, and only then falls
back to FIPS and Tor. The fix routes federation contacts INTO that logic
rather than around it.
Test pins the predicate across every device type, including the two that
failed (Meshtastic, Unknown), and asserts ordinary radio contacts and
stock clients still route exactly as before.
