test(e2e): point doctor-report specs at the v1.4.37 hero-card testids

v1.4.37 lifted the doctor-report card from the export-tile grid to a
hero block on the export page; the test-ids renamed from
`export-card-doctor-report` / `export-action-doctor-report` to
`export-hero-doctor-report` / `export-hero-doctor-report-action`.
The Playwright suite still targeted the old ids and timed out on
every run since. Updates the two affected specs.
