Add wxDragDrop test app and document coverage gaps

Browse source 
- Add dnd/dnd_test.cpp standalone app for HTML5 file drop testing
- Add dnd.spec.ts with 9 E2E tests (all passing)
- Update Makefile.wasm with dnd build target
- Update WHATWORKS.md with DnD status and coverage audit results
- Document identified gaps: wxPropertyGrid, virtual modes, pickers, etc.
- Update wxwidgets submodule with DnD support

Tests: 136 total (15 standalone apps)
Coverage: ~70% of KiCad-critical features

- Browser Print triggers `window.print()` for native browser print dialog
- Page Setup dialog works with margins configuration
### wxDragDrop (HTML5 File Drop) - WORKS ✓
- **Status**: External file drops via HTML5 drag and drop API fully functional
- **KiCad Impact**: HIGH - Loading projects, schematics, PCBs via file drops
- **Evidence**: dnd-01-loaded.png shows test app, dnd-05-drop.png shows file drop processing
- **Tests**: 9/9 pass - App load, handlers registered, dragenter, dragleave, drop, file write, event fire
- **Details**:
- HTML5 drag/drop events (dragenter, dragleave, drop) captured on canvas
- Files read via `File.arrayBuffer()` and written to WASM `/tmp/` filesystem
- wxDropFilesEvent dispatched to target window via C++ callback
- Multiple file drops supported
- KiCad file types (.kicad_pcb, .kicad_sch, .kicad_pro, etc.) work correctly
