Fix dev-mode reconnect storm by persisting mongoose connection state on globalThis instead of a module-level flag that resets on Vite HMR. Eliminate redundant in_season DB query on /rezepte — derive seasonal subset from all_brief client-side. Parallelize all page load fetches. Replace N+1 settlement queries in balance route with single batch $in query. Parallelize balance sum and recent splits aggregations. Trim unused dateModified/dateCreated from recipe brief projections. Add indexes: Payment(date, createdAt), PaymentSplit(username), Recipe(short_name), Recipe(season).
