docs(openapi): add dose-history import and its job-status poll

Documents POST /api/medications/intake/dose-history-import and
GET /api/medications/{id}/intake/import/{jobId}/status, including the
full 16-value MedicationImportSkipReason set the v1.33.0 shape widened
to, read straight from MEDICATION_IMPORT_SKIP_REASONS so the two never
drift again.

Also force-registers MedicationDoseHistoryImportFatalReason into
components.schemas: the 422 description names it, but nothing else
$refs it, and zod-openapi drops unreferenced schemas silently.

+        export shape always refuses at 422 (`json_carries_no_intake_time`): it has no field for when a dose was actually
