Subject: [PATCH 1/2] Add mDNS dep and handle IPv4-only mDNS addr

Add `mdns` to the component private requirements so mDNS symbols are available at build time. In connection_handler.c add a conditional to read the IPv4 address from the mdns result when IPv6 is disabled, falling back to ip_addr_copy for dual-stack builds. This avoids accessing IPv6 fields when LWIP IPv6 support is turned off.
