feat(dpi): Add LAN passive flow analysis (no MITM, no cache)
Real-time passive flow monitoring on br-lan for network analysis: - dpi-lan-collector service watches netifyd flows in real-time - Tracks active clients, external destinations, and protocols - Per-client bandwidth and flow statistics - Protocol/application detection via nDPI - Zero latency impact - pure passive observation LuCI integration: - New "LAN Flows" dashboard view with real-time updates - RPCD methods: get_lan_status, get_lan_clients, get_lan_destinations, get_lan_protocols - Settings panel for LAN analysis configuration CLI commands: - dpi-dualctl lan - show summary - dpi-dualctl clients - list active LAN clients - dpi-dualctl destinations - external destinations - dpi-dualctl protocols - detected protocols/apps Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
