feat(demo): add Playwright browser tests, fix Homepage config mount

- Add Playwright E2E test suite covering all 13 user-facing services
- Fix Homepage HTTP 500 by removing read-only bind mount (:ro) so it
  can create its required logs/ directory
- Pin @playwright/test to exact 1.52.0 to match Docker image browsers
- Add .gitignore entries for auto-generated Homepage files and
  Playwright artifacts
- All 13 Playwright tests passing (Chromium headless)
