1.1.0: Smarter autocomplete + Statistics view

- AutocompleteEngine: MRV heuristic picks the most-constrained slot first
  at each step; historical scoring deprioritises dishes used in recent
  weeks (decay: 0.20 last week → 0.90 four+ weeks ago)
- HomeViewModel: passes last 4 weeks as recentPlans to autocomplete
- StatsView (Premium): streak, weeks planned, completion rate, top 8
  dishes with bar charts, top 6 tags with colour bars — 6 languages
- StoreManager: update product ID to approved bundle-ID convention
- Version bump to 1.1.3 / build 48
