test(e2e): fix wx suite — header deps, port pinning, drop legacy-GL tests, wx+pthread worker fix

Suite went 64 failed → 291 passed / 0 failed:
- Makefile.wasm: compile with -MMD -MP and include .d files — stale objects
  relinked against a newer wx lib crashed apps at startup with "function
  signature mismatch" after any header/vtable change
- playwright(.coroutine).config.ts: pin the server port for the whole run
  (resolvePort from playwright-kicad.config.ts); the 60s freshness window made
  workers restarted after a failure rotate to a dead port (ERR_CONNECTION_REFUSED
  cascade across ~50 tests)
- drop legacy-GL testing: KiCad renders via WebGL GAL (gal-webgl.spec.ts);
  remove minimal_test's OpenGL tab/GLTestCanvas, opengl.spec.ts, GL z-order
  describes, -sLEGACY_GL_EMULATION + gl_immediate_shim.js from the test build,
  and the orphaned GL baselines
- coroutine-pthread repro apps join the `all` target (make clean used to delete
  them while all never rebuilt them); clean no longer eats checked-in JS like
  worker_dom_stub.js
- bump wxwidgets: guard module-eval document access so wx+pthread apps
  (threadpool tests) survive Web Worker eval
