fix(e2e): make the firefox kicad suite pass on GPU-less CI runners

Browse source 
CI runs (Hetzner 27329612719, Ubicloud 27330989479) failed 22/41 identically,
in two buckets, both firefox-environment issues (the suite is firefox-only:
test:kicad -> --project=firefox):

1. No WebGL: headless Firefox can't create ANY GL context on a GPU-less VM
   (blocklist bypass still dies with FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS),
   so the GAL canvas failed and an error dialog blocked every UI flow. Fix:
   run headed under xvfb (GLX + Mesa llvmpipe software GL) with
   webgl.force-enabled — workflows now wrap the e2e step in xvfb-run.

2. pcbnew wasm OOM: the ~190M module OOMs Firefox's optimizing wasm JIT at
   compile ("InternalError: out of memory") and the app never boots. Fix:
   javascript.options.wasm_optimizingjit=false (baseline-only compile).

Both prefs are CI-gated in playwright-kicad.config.ts; local runs keep stock
behavior. Boot got slower (baseline JIT), so the wizard helpers now wait for
the registry to have actual UI ENTRIES (the registry OBJECT exists pre-boot)
instead of clicking into a fixed 10x500ms window.

Validated in a local docker repro of the CI env (playwright:v1.57.0 image,
no GPU): pl_editor canvas, gerbview wizard+canvas, and pcbnew wizard (on a
properly asyncified 187M module) all pass; before the fix they reproduced the
exact CI signatures.

Known-fail left on CI: zoom-cursor — the zoom-in anchors at ~ -P in headed
Firefox (screen-vs-client coordinate mix-up in the wheel->GAL path, headed
mode only); marked test.fixme(CI) pending a wx-wasm-layer investigation.
