Fix Permitted Value for Expression Type Rules

[goodwillpunning]

This commit corrects a display-only bug in the validation results when expression type Rules are used. Previously, the permitted column would display the Rule expression as a String. This commit updates the permitted column to the evaluated expression.

This commit also removes an unused object, Lookups.

@goodwillpunning Do we have any tests on the output reports? I didn't see any changes to tests that change the actual/permitted values. Did I just miss them?

Here I was expecting there to be the following columns.
ruleName - good
passed - good
logic - not present. This should be the SQL expr used to derive the "permitted"
permitted - allowed value or range
actual - the result of the expression value
