feat(messaging,dwn,mesh): route peer messaging + DWN sync + blob fetch via FIPS first

Browse Source 
Migrates the remaining Tor-direct peer call sites to PeerRequest so
FIPS is the default when the peer is federated and running the daemon:

- node_message::send_to_peer / check_peer_reachable: gain a
  fips_npub parameter. Error messages updated to reference both
  transports.
- Callers (api/rpc/network.rs, api/rpc/peers.rs, server health
  loop): look up fips_npub from federation storage by onion and
  pass it.
- mesh::send_typed_wire_via_federation: the spawned background POST
  for the /archipelago/mesh-typed endpoint now uses PeerRequest with
  federation-resolved fips_npub. Signature domain unchanged.
- api/rpc/mesh/typed_messages.rs fetch_blob_from_peer: blob URL
  rebuilt as (base_url, path_with_query) so PeerRequest can append
  the query string after swapping the host. Cap/exp/peer
  parameters are still signed over the content ref itself, so
  transport choice is invisible to the signature.
- network/dwn_sync.rs sync_with_peers: per-peer fips_npub lookup
  before sync_single_peer; health/pull/push each dial through
  PeerRequest, so any DWN peer known to federation gets FIPS.

Left Tor-only on purpose:
- api/rpc/identity/handlers.rs handle_identity_resolve_peer_onion —
  resolving TO a DID, no anchor yet.
- content.browse / preview calls to non-federated peers fall
  through to Tor naturally inside PeerRequest (no fips_npub → skip
  FIPS branch).
