feat: implement TED EU scraper with Playwright

- Add Playwright browser automation for TED EU tender scraping
- Install playwright + chromium browser dependencies
- Scraper successfully finds UK-relevant EU tenders (~11 per run)
- Uses headless Chrome with keyword filtering
- Add SCRAPERS_STATUS.md documentation

All 6 main scrapers now operational (digital-marketplace API still down).
Total active tenders: 626
