Add Playwright projects for Chromium, Firefox, WebKit, iPhone 14, and
Pixel 7 viewports. Chromium runs all specs (01-07); other projects run
read-only specs (03, 06, 07) after Chromium finishes, using project
dependencies to ensure chain state exists.
Coverage audit:
- Tests 01/02 already cover /app/get-krk, /app/cheats as part of flows
- Test 03 verifies GraphQL endpoints
- Test 06 covers wallet + position dashboards
- New test 07 adds landing page and docs smoke coverage
Changes:
- playwright.config.ts: 5 projects (3 desktop browsers + 2 mobile)
- wallet-provider.ts: accept optional viewport/screen for mobile contexts
- 03, 06 specs: pass project viewport to wallet context
- 07-landing-pages.spec.ts: new spec for landing homepage + docs
- e2e.yml: timeout 600→900s for cross-browser matrix, updated comments
