feat: add Gitea integration, E2E booking flow, Docker DNS fix, browser-launcher module

- Add tests/scripts/lib/gitea-client.js: Gitea API client with auth, comments,
  attachments, and Markdown report formatters for visual and console reports
- Add tests/scripts/lib/browser-launcher.js: shared Playwright launch config with
  --dns-resolution-order=hostname-first, realistic UA, and navigateTo() helper
  using waitUntil:'commit' + waitForLoadState('domcontentloaded')
- Add tests/scripts/e2e-booking-flow-v2.js: full E2E scenario for irina-vik.ru
  (register → book service → login → personal cabinet) with Gitea reporting
- Update visual-test-pipeline.js: GITEA_ISSUE env var, Gitea comment+attachment
  posting, browser-launcher integration, waitUntil:'commit' navigation
- Update console-error-monitor-standalone.js: same Gitea + DNS fixes
- Update capture-screenshots.js: browser-launcher integration, DNS fix
- Update docker-compose.web-testing.yml: NETWORK_MODE env var (bridge),
  DNS_RESOLUTION_ORDER, GITEA_USER/PASSWORD env passthrough, e2e-booking service
- Update tests/package.json: pin playwright to exact 1.52.0 (matches Docker image)
- Update .gitignore: add tests/visual/e2e/ for E2E screenshots
- Update .kilo/agents/visual-tester.md: Docker networking note, Gitea scripts,
  e2e-booking service, updated script table
- Update .kilo/commands/web-test.md: Docker Networking section, --issue flag,
  Gitea Integration section, e2e-booking service
- Update .kilo/commands/e2e-test.md: complete rewrite — Docker-based Playwright,
  no more MCP dependency, proper service table, Gitea integration docs
- Update .kilo/capability-index.yaml: add gitea_integration, e2e_booking_flow,
  docker_networking capabilities to visual-tester; add routing entries
