Create UI: some changes don't trigger "unsaved changes" dialog

**Describe the bug in current situation**
In the Create UI code, any time the user modifies a store value (eg, Folio Number) and then tries to exit without saving, the framework should prompt with "You have unsaved changes. Are you sure you want to leave?"

However, some store values are missing some code to enable this. See https://github.com/bcgov/bcrs-business-create-ui/blob/master/src/store/mutations/mutations-model.ts.

The developer will have to determine which store values need this code. (Changes made by the app itself don't need this.)
