Viktor Vaczi bf933104f9 Add wxPrinting test app and verify printing infrastructure works
- Create print_test standalone app testing wxPrintout, wxPrintPreview,
  wxPrinter, and browser print via window.print()
- Add 8 E2E tests for printing functionality (all pass)
- Update WHATWORKS.md: printing now works, 127 total tests, 14 standalone apps
- Remove wxRichTextCtrl from untested (disabled, KiCad doesn't use it)

Key findings:
- Printing infrastructure works out of the box in WASM
- wxPrintout callbacks fire correctly (OnBeginPrinting, OnPrintPage, etc.)
- wxPrintPreview renders preview frame
- Browser Print triggers native print dialog via window.print()
