Adds 172.16.81.125:4433 (the laptop's LAN IP) as the first default relay
so the Android rewrite can be tested against a relay whose logs are on the
same host as the builds and screenshots. On fresh installs the Laptop
relay is pre-selected as index 0. On upgrades from an older cached
settings blob, a one-shot migration unshifts it to the front if missing,
so we don't have to tap through Manage Relays after every reinstall.
Marked "remove once Android rewrite is stable" — the address is a hardcoded
LAN IP that won't be valid in other environments.
