feat: Smart Shopping List + Household bugfixes

Shopping:
- Merged view (default): same ingredient + unit = summed amounts
  (150g Quark + 300g Quark → 450g Quark)
- Shows which recipes need each ingredient
- Toggle between 'Zusammengefasst' and 'Nach Rezept' views
- Alphabetically sorted in merged view

Household bugfixes:
- Fixed bouncy modal animation (removed Framer Motion spring)
- Fixed clipboard copy on HTTP (textarea fallback)
- Fixed logout on join (JWT secrets mismatch in docker-compose)

Also: mounted backend data/ volume for recipe images
