[LPD-1M] [Correct] Use parameter names instead of IDs to find constants

Description

Hardcoding parameter IDs can be error prone, especially when going between production & test CalCat instances. The new ability to use the parameter names makes the intent clearer.

How Has This Been Tested?

Ran notebooks interactively to retrieve constants.
