fix: remove custom test extensions causing Playwright conflicts in CI

- Remove test.extend() from all base-test.ts files
- This was causing "test.describe() called in unexpected place" errors
- Keep only the BasePage class exports
- Tests now use standard @playwright/test imports without extensions

This resolves the Playwright version conflict issues in CI environment.
