Zoltan Papp 5cb6b0d33b [client] Assign the Android TUN address as a host prefix (#7414)
Android 16+ local network protection derives the blocked prefixes from the interface address prefix. A /16 address turns the whole overlay into a local network, so apps without ACCESS_LOCAL_NETWORK cannot reach any peer. Pass the address as /32 and /128 and add the overlay networks to the route list that the Android side turns into VPN routes, on both the initial create and the renew path.
