feat(planner): show score badges for all recipes in RecipePicker

- +server.ts: pass topN=100 so all recipes are scored in one request
- RecipePicker: Empfohlen keeps top 5 with scoreDelta > 0; builds a
  scoreMap from all suggestions; shows green/yellow/red delta badge on
  every recipe in Alle Rezepte that has a score entry
- Extracted scoreBadge snippet to avoid duplication between sections
