feat: add IPv6 prefix fallback and NDP proxy for SLAAC/IA_NA

Add interface address fallback for IPv6 prefix detection when
route-based detection fails (no delegated prefix on LAN). Covers
DHCPv6 IA_NA / SLAAC where prefix is assigned to WAN without PD.
Uses getifaddrs() and Ipv6Inet to handle host bits.

Add NDP proxy sync for on-link prefixes. ISP router uses NDP to
resolve MACs; EasyTier /128 addresses on tun0 won't answer on
physical WAN. Periodic sync (30s) reads /128 routes via netlink
and manages proxy neigh entries. Auto-enables proxy_ndp sysctl.
Returns WAN ifindex from detection; static NDP_WAN_IFINDEX for
sync task. Spawns from provider reconcile when auto-detection
enabled.

Add tests: fallback default route interface, on-link NDP proxy,
interface prefix selection.

Fixes #2333
