Wire the backend's GET uplifts/can-approve tier decision into the
pending row and detail modal actions. Approve/Reject now stay disabled
with the plain 'Requires Tier N role' tooltip unless the backend says
the current user may decide at that tier, so roles the backend refuses
(Dispatcher) never get a clickable action or a refusal toast.
- Gate the Revoke action on the approved queue row and the detail modal
to admin users; non-admins get a disabled button with a plain
'Only admins can revoke uplifts' tooltip and the dialog cannot open.
- Stop nesting an h2 inside DialogTitle in the uplift detail modal
(hydration error) by rendering the title text as a non-heading.
- Handle work-order detail/uplift query 403s quietly in the detail
modal: sections fall back to 'Unavailable' and the queries suppress
the global error toast (QueryCache now honors suppressErrorToast).
- Extract UpliftDecisionDialogs and openUpliftEvidence from the page to
meet the changed-file maintainability gate (complexity 23 -> pass).
