MediaPathReport was only delivered via local signal_hub, so calls
between peers on different relays always hit peer_report_timeout
and fell back to relay — even when direct P2P worked perfectly.
Fix: check peer_relay_fp in call_registry (same pattern as
DirectCallAnswer). If the peer is on a remote relay, wrap in
FederatedSignalForward and send via federation link. Also fix
the cross-relay dispatcher to deliver to BOTH caller and callee
(not just caller), since the report can come from either side.

When peers are on different relays, MediaPathReport can't be
forwarded — causing a 3s timeout and false relay fallback even
though direct P2P works perfectly.
Fix: on timeout, if local_direct_ok is true AND the direct
transport's connection is still alive (no close_reason), trust
the direct path instead of falling back to relay. The timeout
indicates a relay forwarding issue, not a direct path failure.
Also fix ALT build paste URL (paste.tbs.manko.yoga not amn.gg).

Add caller_build_version / callee_build_version (git short hash)
to DirectCallOffer and DirectCallAnswer so peers can identify each
other's build in debug logs. Also log own build at register time.
