fix(mobile): abort uni.request when the platform timeout does not fire

Some uni-app platforms ignore the `timeout` option, leaving the returned
promise pending forever and hanging the calling page with no error path.

Drive the deadline locally: keep a single-shot `finish` guard so success,
failure and timeout can only settle once, and on timeout call `task.abort()`
before rejecting so the in-flight request is released instead of leaking.
