fix(ci): switch fetch-test-timing.mjs to Codecov's test-analytics endpoint

test-results/ is deprecated -- confirmed live, running test-timing-refresh.yml
via workflow_dispatch returned a 301 pointing at test-analytics/ instead
("This endpoint has been deprecated. Please use /test-analytics/ instead.").
Verified via Codecov's own live OpenAPI schema that the replacement returns
the identical PaginatedTestrunList wrapper and Testrun field shape, so this
is a pure URL fix -- nothing else in the aggregation logic needed to change.
