fix(android): app crashes if the phone rotates while it's starting

[SRWieZ]

What's wrong

On Android, if the phone rotates (or switches dark mode) in the first moments after launch, the app crashes:

java.lang.UnsatisfiedLinkError: No implementation found for void
  com.nativephp.mobile.ui.nativerender.NativeElementBridge.nativeElementWriteEvent(int, int, int, byte[])
  at NativeElementBridge$Companion.sendNativeEvent(NativeElementBridge.kt:873)
  at MainActivity.sendOrientationChanged(MainActivity.kt:513)
  at MainActivity.onConfigurationChanged(MainActivity.kt:508)

Seen on a Xiaomi running Android 16, 1.5 s after launch. It depends on timing, so it's hard to trigger on purpose: turn the phone right as the app opens.

Why

sendNativeEvent() calls a native (C) function. That function only exists once the PHP runtime has loaded, and the runtime loads lazily, a moment after the screen appears. A rotation or dark-mode change that arrives before that point calls a function that isn't there yet.

What this does

If the runtime isn't loaded yet, the event is dropped (with a log line) instead of crashing. Nothing is lost: PHP reads the orientation and appearance itself when it starts. One file, iOS untouched.

Does it need to return if it fails? Can't we just log it and continue as we were before?
