feat: Generali tab, time-based auto theme, AI cost from real data
- index.html: new Generali tab (first, active) with Language/Currency/
Theme/Screensaver/ZeroWaste/Export; old tab-language removed;
screensaver timeout select uses form-input style; asset v=20260518a
- app.js: auto theme = time-based (20:00-07:00 dark, not system pref);
removed matchMedia listener; added 5min setInterval for auto re-check;
removed Bring! token row from Info tab (internal implementation detail)
- api/index.php: gemini_usage - removed all cache-estimation code;
month/year_stats from ai_usage.json only
- data/ai_usage.json: data-driven baseline estimate for 2026-05:
~4.4M in + ~1.3M out from 8374 inferred historical calls (102 recipes,
555 price lookups, getStats loop pre-fix, smart cron runs, etc.)
= ~EUR 1.32 at 2.5-flash rates; new calls tracked precisely from now
- translations: settings.tab_general added; theme.auto updated to
'Automatico (orario)' / 'Automatic (time of day)' / 'Automatisch (Tageszeit)'
