feat(a11y): add axe-core Playwright scorecard for 10 key routes

- Installs @axe-core/playwright at workspace root
- Creates e2e/a11y/scorecard.spec.ts scanning /, /search, /listings/[id],
  /listings/create, /login, /register, /dashboard, /agent/[id],
  /inquiries, /admin/moderation
- API mock layer lets pages render with stubbed JSON so axe sees real DOM
- Critical/serious violations fail the build; moderate/minor are recorded only
- Writes per-route JSON reports to e2e/a11y/reports/ (committed for before/after diffing in PRs)
- Adds dedicated "a11y" Playwright project in playwright.config.ts
- Pre-existing API unit test failures are unrelated to this change
