feat: add interface traffic counters as fallback telemetry when conntrack flows unavailable

Browse Source 
Add interface_traffic collection in agent to aggregate VM/LXC network counters by vmid/nic with tap/fwln/fwpr/fwbr interface ranking, implement collect_interface_traffic to select best interface per VM NIC and format as flow-like records with rx/tx bytes/packets, add collect_flow_diagnostics to capture conntrack binary path and kernel bridge/netfilter settings for debugging, update workload_insights endpoint
