feat: working Puppeteer scraper for Promofarma

- Added Puppeteer with Chrome in Docker
- Scraper extracts products using data attributes
- Added /api/scrape endpoint
- Tested: 10 products scraped from Promofarma

The scraper now works with Promofarma's HTML structure which uses
data-name, data-pvp attributes on article elements.
