fix(open-webui): use current request-handler API to fix the build

The request handlers were written against an older caching API that dev has
since refactored ('TanStack Query as single source of truth'), breaking the
Turbopack build with a module-not-found on ./lib/cached-integration-request-handler.

- use createIntegrationRequestHandler from ./lib/integration-request-handler
- replace cacheDuration(dayjs)/queryKey with cacheTtlMs (ms)
- update the router consumers: getCachedOrUpdatedDataAsync -> getDataAsync and
  per-call invalidateAsync() -> handler-level invalidateCache()
