Agent nodes store the create form's placeholder in nodes.address
('agent', port 2053; NodeFormModal.buildPayload). The export fallback
chain treated it as a real node address, so every host-less inbound on
an agent node produced links like vless://...@agent:31324.
SubService now loads agent_nodes bindings alongside nodes (latest
last_seen per node, same rule as the node list) and resolves an
agent-managed node's export address through the single convergence
point agentNodeAddress(nodeID): telemetry IPv4, then IPv6, then ""
so the chain continues to listen/public/request host and can never
emit the placeholder. Host-bound inbounds and traditional nodes are
untouched. GetInboundOptions applies the same substitution via
agentAdvertisedAddresses so the frontend share/QR/WireGuard feed
never sees the placeholder either.
