fix(android): migrate OPPO & vivo push SDKs to new API versions

- OPPO HeytapPush V3.7.1: fix ICallBackResultService package (mode→callback),
  update init() signature (remove appKey/appSecret), update all callback
  method signatures, remove deprecated onReceiveMessage/onNotificationTapped
- vivo Push v4.1.3.0: replace OpenIMInterface+OpenClientPushManager with
  OpenClientPushMessageReceiver+PushClient, async getRegId
