Update mDNS traffic simulation in the Nexus platform to flow through the simulated infrastructure link. This ensures mDNS packets are automatically written to the PCAP file generated by the simulated infrastructure link. Changes: - Wrap mDNS messages in UDP/IPv6 headers and enqueue them on the simulated infrastructure interface (InfraIf). - Implement a new SendUdp overload in InfraIf that accepts a Message payload. - Update InfraIf::Receive to intercept mDNS UDP packets (port 5353) and deliver them to the Mdns module. - Remove the dedicated ProcessMdns loop and manual PendingTx list from Core and Mdns, consolidating traffic processing through InfraIf. - Initialize Mdns with a reference to the Node to allow access to InfraIf. - Add GetMulticastAddress static helper to Mdns for 'ff02::fb'.
