WHY IT NEEDS A POLICY

Why jsm.updateForm needs a policy

This tool replaces/updates a form in Jira Service Management. It modifies existing data but is reversible (form can be replaced again). No code execution, deletion, or financial impact. 'Replace' implies a full overwrite which could discard previous form configuration, but the action is categorized as Write since the data isn't permanently destroyed.

From the tool's definition Replace a form — indicates full replacement/update of an existing JSM form
