<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Small React Query configuration change that only affects refresh
timing for the Activity list; no auth, security, or data-shape changes.
> 
> **Overview**
> Activity list transaction fetching no longer forces periodic refresh:
it removes `refetchInterval` and the explicit `refetchOnWindowFocus:
false`, and uses the shared `STALE_TIMES.TRANSACTIONS` constant instead
of a hard-coded 15s `staleTime`.
> 
> This shifts when the list refetches to React Query’s default triggers
and the centralized staleness configuration (while still allowing
callers to override via `options`).
