feat: Info tab v3 — clean month/year stats, currency to Info tab, Gemini costs from .env

- .env: GEMINI_COST_* rates configurable (4 new vars, defaults to current Google pricing)
- api/index.php: GEMINI_COST defines read from env() with fallback; added SHOPPING_NAME_CACHE_PATH
- api/index.php: gemini_usage output — clean month_stats/year_stats (no tracked/retro split)
  updated token estimates: price 700/250, shelf 650/120, cat 280/40, shopping_name 250/40
  added 'pricing' key to response (current rates); removed food_facts from estimate
- index.html: currency selector moved from tab-api to tab-info as first card (global setting)
- app.js: _renderInfoTab() rewritten — just month + year sections, no retro framing
  cost displayed in user's currency (price_currency) with expanded multi-currency conversion
- translations: settings.info.currency_title/hint/year_label added; retro/tracked keys removed
