Pouzor cf7777e0af feat: improve IoT device detection via two-phase scan and mDNS discovery
- Two-phase nmap: ARP sweep first to find all alive hosts (incl. IoT with
  no open TCP ports), then port scan only alive hosts
- mDNS/Bonjour discovery via zeroconf for Shelly, ESPHome, HomeKit devices
- Add CoAP ports (5683, 5684, 4915) to port scan and IoT type hints
- Expand MAC OUI table with Shelly, Espressif, Sonoff, Tapo, Hue, IKEA, Tuya
- IoT vendor MAC takes precedence over generic HTTP port type hints
- Reorder suggest_node_type priority: iot now beats server
