1.2.0: offer code redemption + share link alongside export image

- "Redeem promo code" button in PremiumView via offerCodeRedemption
  (hidden on Mac where the sheet is unavailable); entitlement re-checked
  on success — unblocks influencer/blog promo campaigns
- System share sheet now includes a localized text with the mealmood.app
  link next to the exported image (viral loop no longer QR-only)
- 2 new strings × 6 languages
