fix(e2e): route pcbnew-family specs to bundled Chromium on CI

The xvfb/WebGL fix (f37ddc4) took CI from 22 to 11 failures (identical on
Hetzner 27343415331 and Ubicloud 27343416511) — everything left is the
pcbnew family, still dying at wasm compile: pcbnew's ~190M debug module
exceeds SpiderMonkey's per-process code budget on x86-64 even with the
baseline-only JIT (the same module compiles on arm64, whose denser code
fits — which is why the local arm64 repro passed). No pref raises that
limit; V8 handles the module fine.

New CI-only 'chromium-ci' project (bundled Chromium, headless, SwiftShader
via --enable-unsafe-swiftshader) carries pcbnew/pcbnew-collab/load-pcb/
load-pcb-probe; the firefox project ignores them on CI. Workflows call the
new test:kicad:ci script which runs both projects. Local test:kicad is
unchanged (firefox everywhere, system Chrome for headed runs).

Validated under x86 emulation (linux/amd64 playwright image on Rosetta):
the pcbnew wizard test passes on chromium-ci in 23s against the fresh
v130-postprocessed 192M module.
