Guard statusBarShow/statusBarHide against detached decorView

Summary:
`statusBarShow()` and `statusBarHide()` access the window's `decorView`, which throws `IllegalArgumentException` when the decorView is not attached to the window manager. This can happen for extra windows (dialogs/popups) whose decorView is detached independently of the host activity's lifecycle, or when status bar visibility is updated during teardown.

Guard both functions with `if (!decorView.isAttachedToWindow) return` so the fix protects every caller at the source. The guard is a no-op during normal operation (the decorView is always attached) and only short-circuits during the teardown race.

Changelog:
[Android][Fixed] - Prevent `IllegalArgumentException` crash in `statusBarShow`/`statusBarHide` when the window decorView is detached
