test(e2e): cover the Apple Health export import end to end

Upload a synthetic export.zip on the import card, wait out the queued
job through the card's own status poll, and read the imported readings
back off the measurements list with the units the parser resolved.
Weight, the blood-pressure pair and the step count are asserted; the
walking-distance case is written and skipped, naming issue #944 — a
record written in km lands as metres today, and the assertion is kept
at full strength so the fix has something to turn green.

The refusing control uploads a valid ZIP with no export.xml: the card
surfaces the extractor's own refusal and the account's Apple Health row
count does not move.

Measurement rows now carry data-measurement-type / -value / -unit
beside the rendered cell, on both the desktop table and the mobile
list, so an assertion binds to the reading rather than to whatever the
locale formatter made of it. The import card's error line gets a test
id for the same reason.
