The issue-detail right-rail Token usage card is fed by useQuery(issueUsageOptions(id)),
but the realtime task: handler only invalidated ["issues","tasks"]. As a result the
card only refreshed on remount, so consecutive runs on the same issue left the
numbers stuck until the user navigated away and back. Mirror the existing tasks
invalidation with a prefix invalidation of ["issues","usage"] so any task
lifecycle event refreshes the aggregated usage numbers.
