Playwright scraping for FLAT/Pitbar; web UI display-only

- Install Playwright + Chromium; add shared browser singleton (playwright.server.ts)
- Rewrite flat-nishiogikubo scraper: Wix calendar via headless browser,
  month navigation via date picker, extracts .WPczEB/.ExCBIq selectors
- Rewrite pitbar-nishiogikubo scraper: freecalend.com via headless browser,
  parses cal-{member}-{year}-{month}-{day} cell IDs
- scraper-runner: close shared browser after each run with closeBrowser()
- Remove all scrape trigger buttons from web UI (events index, venues page);
  remove /api/scrape and /api/scrape-status from routes.ts
