Code Review
This pull request addresses a critical IllegalStateException on Android by correctly handling the VideoAdPlayer.release callback, which now resets the ad container's state. A null check has been added to the pauseAd method to prevent calls on an uninitialized MediaPlayer. Additionally, a race condition in _startAdProgressTracking is resolved by ensuring ad duration is available before use. The changes are well-supported by new, targeted unit tests that validate the fixes.

… uninitalized `MediaPlayer` (flutter#9861) The `AndroidAdDisplayContainer` wasn't handling the callback of `VideoAdPlayer.release`. It looks like the IMA SDK calls `VideoAdPlayer.release` -> `VideoAdPlayer.pauseAd` -> `VideoAdPlayer.stopAd` when `AdsManager.destroy` is called. The `AdDisplayContainer` now resets state on release and `pauseAd` only calls pause when media player is not null. Also fixes race condition where `AndroidAdDisplayContainer._adDuration` would be set to null while retrieving the current position of the `VideoView`.
