DHCP hostname: send net.hostname in DHCP requests

Browse Source 
- aes67_net: esp_netif_set_hostname() before the interface starts, and
  in the net apply callback (takes effect at the next lease renewal).
- Verified: the router's DNS (lan.apointless.space) resolves p4-aes67
  to 192.168.192.244.

## Network
- Default: one untagged interface. VLAN split option: AES67 untagged + internet tagged (inet.vlan_id/pcp) using the ESP-IDF vlan_support approach (examples/network/vlan_support, ESP32-P4 supported). AES67 side has no gateway; default route and DNS are on inet.
- PTP, RTP, SAP and IGMP bind to the AES67 netif. HTTP server filters on `web_on`.
- DHCP sends net.hostname (option 12), so the router's lease list / local DNS shows it; after a rename it applies at the next lease renewal.
- mDNS (espressif/mdns): `<net.hostname>.local` plus the web UI as `_http._tcp` port 80. A hostname change applies live (the new name answers after ~1 s of RFC 6762 probing).
- LLDP (IEEE 802.1AB), transmit only, own code (not in IDF/lwIP): every 30 s, TTL 120 s, plus immediately on a new IP or hostname. TLVs: chassis ID and port ID = MAC, port description "eth0", system name = net.hostname, system description = project + firmware version, capabilities station-only, management address = IPv4. With the VLAN split, send it on the AES67 (untagged) side; the 802.1 port VLAN ID TLV can be added then.
- Switch port: AES67 as native/untagged VLAN, internet tagged, PoE on. IGMP snooping + querier on the AES67 VLAN.
