Clean up test infrastructure and fix test assertions

- Replace test.skip() with proper expect() assertions when app fails to load
- Remove button-finder utility (no longer needed with element registry)
- Remove kicad tests (tested separately)
- Add findByName/clickByName helpers for bitmap buttons
- Fix element lookups: use clickByName for bitmap buttons, clickTreeItem
  for treebook pages, selectComboItem for wxChoice items
- Add SetName() to shape buttons in bitmapbuttons_test.cpp
- Remove verbose logging from print and threadpool tests
- Update README to reflect current test infrastructure
