fix: Analyst ratings abort without reason on overview page

- trpcQuery/trpcMutate now throw 'Request timed out (8s)' instead of
  generic 'The operation was aborted.' so users know WHY the request failed
- AnalystRatings adds cancelled guard (race condition fix) so stale
  promise results from symbol changes are ignored (matches OverviewPanel
  pattern)
- Add Retry button on error state for timeout or other failures
- useEffect cleanup returns cancelled flag setter
