Add multi-country ITAD deals, configurable currency, and per-source filtering

- ITAD deals can now be fetched from multiple countries simultaneously via
  ITAD_COUNTRIES (e.g. US,CA,GB,DE). Deals are merged across regions and
  deduplicated by game+shop, with the first country taking priority.

- Prices from non-USD regions are normalised to USD using exchange rates
  so filtering (max price) works consistently across countries.

- ITAD results are now sorted by newest deals first (client-side by
  timestamp) instead of only by highest discount, reducing missed deals.

- Default fetch limit raised from 20 to 100 to capture more deals.

- Display currency is now configurable: DEFAULT_CURRENCY sets the primary
  currency shown first, EXTRA_CURRENCIES sets additional ones. All
  Frankfurter-supported currencies are available with proper symbols.

- Filtering is now per-source with dedicated env vars:
  CHEAPSHARK_MIN_DISCOUNT, CHEAPSHARK_MIN_RATING, CHEAPSHARK_MAX_PRICE,
  ITAD_MIN_DISCOUNT, ITAD_MAX_PRICE, ITAD_DEALS_LIMIT. Shared fallbacks
  (MIN_DISCOUNT_PERCENT, MAX_PRICE) are still supported. Legacy
  MAX_PRICE_USD and MIN_DEAL_RATING continue to work as fallbacks.
