Subject: [PATCH] feat: add WiFi companion radio env for LilyGo T3-S3 V1

Mirrors Heltec_v3_companion_radio_wifi 1:1; only the `extends` ref
changes. The WiFi runtime path (#ifdef WIFI_SSID in
examples/companion_radio/main.cpp) already ships for Heltec V3 /
RAK3112 / T-Beam Supreme, so this is a pure config-only enablement.

Also enables the _companion_radio_wifi suffix in build.sh's
companion release loop, unblocking the 16 already-merged WiFi envs
that are currently built locally but never shipped via the
companion-vX.Y.Z release tags.

Tested on hardware: device joins WiFi, OLED shows IP, TCP port 5000
reachable, companion protocol responds correctly to APP_START and
DEVICE_QUERY frames.

Refs #387, #1134.
