Patch 5.9.1, Carried Home

The curation script once searched in one place,
fms_core was the only domain.
Now it asks each entity, "Which app's your base?"
And apps.get_model finds it again.

In fms_report, four models ran wild,
Report and MetricField, plus two more,
ProductionData and Tracking, defiled
by plain models.Model, as before.

Now TrackedModel gives them a past:
who made them, who changed them, and when,
with a deleted flag and stamps that last,
so history's kept for them then.

Migration 0003 adds the fields,
with defaults to fill every gap,
and the patch from the branch, its work now sealed,
rejoins master: a hundred forty lines, a wrap.
