The previous static key={c.id} let React reuse the same <TableRow>
element across refetches, so animate-row-flash only played on
initial mount and on the first render of a brand-new claim_id.
Updated rows whose claim_id was unchanged never re-flashed.
Re-keying on `${c.id}-${dataUpdatedAt}` re-mounts the row on
every refetch (initial load, filter change, parse invalidation),
so the 1.2s accent-tint flash replays each time.
Also: README's 'Frontend unit tests (when added)' is stale — npm
test now exists and runs 3 passing tests.
hooks: add dataUpdatedAt: 0 to the !isConfigured fallback return
so the pages type-check.
