Relay nodes run in store-and-forward mode with no local gate configs,
so gate_manager.can_enter() always returned "Gate does not exist" —
silently rejecting every pushed gate message. This broke cross-node
gate message delivery entirely since no relay ever stored anything.
Relay mode now skips the gate-existence check after signature
verification passes, allowing encrypted gate blobs to flow through.
