Changeform submitline actions

Changeform submitline actions operate differently from other custom actions in Unfold. When triggered, these actions first save the form data (equivalent to clicking the 'Save' button) before executing any additional logic. This means that by the time your custom action code runs, you'll be working with an already saved instance of the model. This workflow ensures data consistency by guaranteeing that all form changes are properly saved before any custom operations are performed.
