Implements first-boot Wi-Fi setup with no companion app required: a SoftAP + captive portal (DNS wildcard redirect, DHCP option 114, HTTP form) lets the user submit Wi-Fi credentials from any browser. On submit, credentials are saved to NVS and the device switches to STA mode; on subsequent boots it reconnects automatically via stored credentials. dns_server.c/.h are vendored from ESP-IDF's official captive_portal example (Unlicense/CC0). Requests both link-local and global IPv6 addresses once the STA connection has an IPv4 address (not on WIFI_EVENT_STA_CONNECTED -- esp_netif_create_ip6_linklocal() reliably fails there because esp-netif's own handler, which marks the lwIP netif "up", hasn't run yet due to event-handler registration order). Verified end-to-end on real ESP32-C6 hardware: SoftAP comes up, credential submission works, STA reconnects on reboot, and both a link-local and a router-assigned global IPv6 address are obtained via SLAAC.
