Add ember-styleguide v2 from PR branch, fix macros in dev builds

- Add ember-styleguide from git ref (NullVoxPopuli-ai-agent/ember-styleguide#convert-to-v2-addon)
- Register ember-styleguide services (navbar, progress) in app.js
- Restore EsHeader/EsFooter in application.hbs
- Add @ember/test-waiters and ember-concurrency as dependencies
- Fix babel filter to use function-based ID matching for pnpm deep paths
  (regex-based exclude doesn't work with pnpm's nested node_modules)
- Process @ember/test-waiters through babel for macros compilation
- All @embroider/macros compiled away in both production AND development builds

Tests: 68/205 pass (remaining failures from removed v1 addons like
ember-leaflet, ember-responsive-image, and percy)
