fix: skip pointer lock request on unsupported devices (iPad)

On devices where pointer lock isn't supported (like iPad), clicking
the map would try to request pointer lock on every click and return
early, preventing region clicks from being processed. Now we check
if pointer lock is supported before trying to request it.
