fix: upgrade Node 18 to 22 and fix Puppeteer compatibility

- Switch from Alpine to Debian slim for correct Chromium architecture
  (fixes ARM/Apple Silicon support)
- Upgrade Puppeteer 21 to 24, use system Chromium via PUPPETEER_EXECUTABLE_PATH
- Replace removed page.waitForTimeout() with setTimeout
- Set NODE_ENV=production in Dockerfile to prevent pino-pretty import
- Improve error logging with Pino's { err: error } pattern
- Add build: . to docker-compose for local development builds
