feat(integrations): say where an imported Google Health history ends

The two status routes publish backfillEnded: each data type whose
backfill stopped short of the start of its history, with the instant it
reaches back to and whether the horizon or a walk that stopped moving
ended it. The integration card lists them in place of an import that
would otherwise read as still loading, in all seven locales.
