Fixed various issues with debug window

- Fixed Shadow Atlas index.
- Fixed DebugManager.instance.displayRuntimeUI breaking after domain reload
- Removed wrong "Last" entries in material debug.
- Fixed Frame Settings debug not being removed correctly on camera disable.
- Frame Settings debug layout is now the same as the regular UI.
