[Metrc] Support new: CA Required Lab Test Batches based on Item Category per CA Testing Rules

A new feature of Canix for [Metrc] California customers that aligns mandatory test batches directly with product categories. Metrc's has introduced a change, rather than requiring lab licensees to select the appropriate lab tests for the product being tested, Metrc will enforce required lab test batches based on item category based on State testing rules.

: Package-specific lookups fetch required lab tests using the package ID, rather than determining requirements based on item category.

Canix will retrieve required lab test batches for each item category, and conversely, submit them when creating testing packages.

Canix will perform a daily fetch from Metrc CA to ensure we keep the item categories requiring tests aligned with any updates.
