Subject: [PATCH] test(export): coverage for export-section + endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an e2e smoke (`e2e/settings-export.spec.ts`) that:
  1. Asserts the five export cards render with stable testids
     (`export-card-doctor-report` etc) so the consolidated UI can't
     silently regress to fewer than five cards.
  2. Drives the Measurements CSV download end-to-end with the API
     stubbed — the browser-side wiring is what we lock in here, not
     the route's DB query (already covered by the integration test).

Component test coverage already landed in commit 621109c
(`export-section.test.tsx`); unit + integration coverage for the
endpoints landed in commit 226cac4 — this e2e is the missing piece.

+/**
+ * v1.4.16 phase B7 — Settings → Export consolidated UI smoke.
+ *
+ * Validates that:
+ *   1. The five export cards are all rendered with their stable testids.
+ *   2. Clicking the Measurements CSV download button fires a real
+ *      browser download — proving the new `/api/export/measurements`
+ *      endpoint is reachable from the browser end-to-end.
+ *
+ * The other CSV / JSON cards share the same code path; one happy-path
+ * download is enough to lock in the wiring without doubling the e2e
+ * runtime.
