Viktor Vaczi 961455ef54 Add baseline screenshots and visual regression testing ...

Add infrastructure for visual regression testing of wxWidgets WASM rendering:

- Add 121 baseline screenshots capturing all UI states tested by Playwright
- Add scripts/compare-screenshots.sh to compare test results vs baseline
- Update tests/WHATWORKS.md with documentation on screenshot comparison
- Update wxwidgets submodule with dialog refactoring

The baseline screenshots cover:
- Main app tabs (Controls, Text Input, Drawing, Lists, OpenGL, Grid, Dialogs)
- Standalone test apps (menu, toolbar, layout, aui, clipboard, filedialog, etc.)
- Dialog/MessageBox rendering (info, yes/no, error, custom dialogs)
- OpenGL rendering tests (immediate mode, vertex arrays, matrix ops)
- UI interactions (dropdowns, tab switching, z-ordering)

Use ./scripts/compare-screenshots.sh to check for visual regressions.
Small byte differences (<2%) are typically timestamps, not visual changes.
