mesh.send-content was failing with "Message too large for LoRa: 624
bytes (max 160)" because a single ContentRef envelope (cid + onion +
cap_token + thumb) dwarfs a LoRa frame. Add a federation Tor fallback:
- New POST /archipelago/mesh-typed endpoint accepts
{from_pubkey, typed_envelope_b64, signature}, verifies ed25519 over
the raw wire bytes, and injects the decoded envelope into MeshState
via a new MeshService::inject_typed_from_federation helper. This
shares the same dispatch match as LoRa receives via a new pub(crate)
handle_typed_envelope_direct extracted from handle_typed_message.
- MeshService::send_typed_wire_via_federation POSTs the signed wire to
a peer's onion over TOR_SOCKS_PROXY and records a local Sent record.
- handle_mesh_send_content looks up the peer's onion in federation
storage and routes via federation when available, falling back to
LoRa only when no federation presence is known (still fails on
oversized — chunking is Phase 4).
