fix(admin): count every record class in the upload summary

The total shown after a backup upload skipped the nutrient day totals, so a file
that carried and restored them reported fewer records than it held. Same defect
as the payload gaps this branch closes, on the reporting side. Counts the
nutrient days, the health profile and the custom metrics with their readings.
