add inset based margins to RedBox (facebook#46391)

Summary:
Pull Request resolved: facebook#46391

**Issue:**
RedBox displays early error before JS Error handling is properly setup.
On Android 15, targetSdk 35 (forced edge-to-edge), dialog overlaps with system bars making it difficult to use.

**Solution**
Add inset based margins so content does not overlap with system bars.

Changelog:
[Android][Fixed] - RedBox content overlapping with system bars on Android 15 forced edge-to-edge
