refactor: migrate pricing entities to DML models (#10335)

Fixes: FRMW-2810

## Breaking changes
There is only one breaking change

- The `min_quantity` and `max_quantity` properties are now consistently typed as numbers. Earlier, it was [typed as numbers](https://github.com/medusajs/medusa/blob/develop/integration-tests/http/__tests__/price-list/admin/price-list.spec.ts#L68-L69) in some API responses and as [string in others](https://github.com/medusajs/medusa/blob/develop/integration-tests/http/__tests__/price-list/admin/price-list.spec.ts#L186-L187). I did not go to the bottom of this inconsistency, but the tests reveals them.
