Remove redundant Buff163 integration causing CORS errors

The buff163Integration.js was old code that:
- Tried to fetch directly from Buff163.com (causes CORS errors)
- Was redundant - multiMarketPricing.js already gets Buff prices from our API
- Caused console errors: 'Error fetching Buff163 price: TypeError: Failed to fetch'

Changes:
- Deleted src/buff163Integration.js
- Removed from manifest.json content_scripts
- Removed references in content.js

Now all market prices (Buff163, Skinport, CS.MONEY) come from our own
API endpoint: /api/price/{itemName} - no more CORS errors!
