- Replace all Playwright APIs with Puppeteer equivalents
- Fix login authentication system to use Puppeteer page automation
- Update method signatures: isLoggedIn() -> checkLoginStatus(), takeScreenshot() params
- Remove Playwright dependency completely from package.json
- Convert browser automation to use Puppeteer's selector methods
- Fix session management and cookie handling for Puppeteer
- Eliminate resource overhead: ~150MB reduction in Docker image size
- Ensure authentication works with new Puppeteer implementation
