* Add change name rule for transaction

* Use HTML template in the ERB, clone and inject those templates from the stimulus controller

* Put back the ai_enabled check

* Update docs

* Example of what no case statement would look like

* Remove action_type and needs_value now that controller is injecting templates/hiding action target
