NIFI-15957 - Do not resolve parameter references when displaying parameter contexts

Summary

NIFI-15957 - Do not resolve parameter references when displaying parameter contexts

Following changes done in NIFI-15829 we can now have parameters referencing inherited parameters. However, when showing the parameter contexts in the UI the parameters that are referencing parameters are now showing the resolved value instead of the raw reference. While this is not an issue, it can be confusing and we should display the raw reference.

Example:

MyInheritedParameter => MyInheritedValue
MyParameter => #{MyInheritedParameter}

Showing the parameter context in the UI, it would show:

MyParameter => MyInheritedValue

(even though the flow definition does have the reference)

We want to always show:

MyParameter => #{MyInheritedParameter}
