✨ feat(bestdebrid): add BestDebrid web-login provider

- New BestDebrid web-login option (BrowserWindow + session.fetch)
- Uses bestdebrid.com/api/v1/generateLink with browser session cookies
- Login via BestDebrid website in embedded browser window
- Toggle "BestDebrid per Web-Login statt API-Token verwenden"
- Provider label shows "BestDebrid (Web)" or "BestDebrid (API)"
- Session persistence respects "Token merken" setting
