feat: CSV-Import/-Export für Gerichte/Allergene/Zusatzstoffe, RSS-Fix für mehrere Essenszeiten
CSV-Import/-Export (Gerichte, Allergene, Zusatzstoffe): neue Export-/ Import-Routen unter app/api/*/export und */import, hand-geschriebener CSV-Parser/-Serializer (lib/csv.ts, keine neue Abhängigkeit), Upsert über Kürzel (Allergene/Zusatzstoffe) bzw. exakten Namen (Gerichte, mit Ambiguitäts-Check bei Namensdopplung). UI-Buttons in DishManager und CodeListManager. RSS-Feed: <content:encoded> zusätzlich zu <description> ausgeben, da mehrere Feed-Reader description als kürzbare Vorschau behandeln und dadurch bei mehreren Essenszeiten pro Tag nur die erste zeigten. Version 1.7.0. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
