Fixing missing support for "Subcategory Levels" parameter in contacts category view

[artur-stepien]

This adds the support for Subcategory Levels in Category tab of List Contacts in a Category view. Currently, this setting is not applied in the query, so using it will not allow viewing all contacts in the category and its subcategories.

Summary of Changes

Added state entry and query filter for this parameter.

Testing Instructions

• Create a contact category called All contacts
• Create a contact category called A and set the parent as All contacts
• Create a contact category called B and set the parent as All contacts
• Create contact Contact from A and place it in A category
• Create contact Contact from B and place it in B category
• Create a menu item of type List Contacts in a Category, chose category All contacts and make sure in Category tab Subcategory Levels is set to All or any positive value
• Save and head to the recently created menu item in front-end

Actual result BEFORE applying this Pull Request

There should be no contacts displayed in this view.

Expected result AFTER applying this Pull Request

All contacts from category A and B will be displayed.

Yeah, but what is it complaining about. The lack of alignment between = signs?

Without the patch I see just the Subcategories list. With the patch I see the actual contacts in Categories A and B.
