Add some reasonable minimum and recommended inventory levels to items in the seed

[cielf]

Summary

The minimum and recommended inventory levels show up in the low inventory report on the dashboard. It's a nice to have to potentially have some values showing up there for demo / manual testing purposes.

Details

For half of the inventory item in the seed for the first organization, set the minimum value to a nice round number (let's say something divisible by 10 between 0 and 1000), and the recommended inventory level to a value that is between the minimum value and 10000, and is also divisible by 10

Criteria for completion

• [ ] items in seed contain minimum and recommended values as described above.
