"""Create new ParameterTemplate and Parameter models.
Ref: https://github.com/inventree/InvenTree/pull/10699
These models have been migrated from the following (existing) models:
- part.PartParameterTemplate -> common.ParameterTemplate
- part.PartParameter -> common.Parameter
To preserve the existing data, we will use the existing database tables.
For this to work, the existing models (part.PartParameterTemplate and part.PartParameter)
must have already had schema and migrations applied:
- part/migrations/0144_auto_20251203_1045.py
- part/migrations/0145_auto_20251203_1120.py
