Note

Low Risk
Narrow revert in balance-fetch caching only; may increase duplicate API calls during force-refresh bursts but restores correct fresh-balance behavior.

Overview
Reverts #9591 so AccountsApiDataSource again passes staleTime: 0 / gcTime: 0 to the Accounts API balance client when forceUpdate is true, instead of a 100ms cache window.

Forced balance refreshes (account switch, post-tx refresh, subscription handoffs, etc.) are meant to skip TanStack Query reuse; the short window could still serve a cached response. The unit test is renamed/updated to assert full cache bypass, and the changelog records the fix under Fixed.
