ci(ubicloud): add the wxWidgets e2e suite to the run

Host-side wxUniversal build + wx test apps (build-wxuniversal-wasm.sh /
build-wasm-test.sh, mirroring the dispatch-only ci.yml) followed by
`npm run test` before the KiCad e2e. The wx suite runs on bundled headless
Chromium; several specs use WebGL (gal-webgl.spec.ts), so the chromium
project gains a CI-gated --enable-unsafe-swiftshader launch arg — without
it newer headless Chromium refuses software WebGL on the GPU-less runner.
First time this suite runs on a working CI runner; treat as experimental.
