fix: Disable Firefox/WebKit/Mobile browsers in Playwright config

- Only run tests on Chromium since we only installed Chromium browser
- Disable Firefox, WebKit, Mobile Chrome, and Mobile Safari projects
- This fixes the 'Executable doesn't exist' errors for missing browsers
- Significantly reduces test execution time in CI
