Messaging a federation-only peer (e.g. 'Arch Dev') failed with 'Missing
contact_id'. The UI gave federation-only rows a *negative* placeholder
contact_id derived from a DID hash, but the backend parses contact_id as u64,
so a negative value deserialized to None. The negative id also never matched
the positive federation-synthetic id that federation-routed messages are stored
under, so those threads looked empty.
- Frontend: derive the SAME positive federation-synthetic id the backend uses
(federationContactId mirrors federation_peer_contact_id) so mesh.send accepts
it and messages thread correctly.
- Backend: send_typed_wire now resolves a federation-synthetic contact_id from
nodes.json when it isn't in the live mesh peer table (radio-less node),
instead of bailing 'Unknown federation peer'.
