WHY IT NEEDS A POLICY

Why update_form needs a policy

This tool creates or modifies form configuration data reversibly. While it replaces the entire configuration (a somewhat aggressive write), the operation is not destructive/irreversible because configurations can be updated again. The impact is scoped to form settings rather than permanent deletion.

From the tool's definition Tool description states it 'Updates the form configuration' which modifies existing data; the note that 'entire configuration is replaced' indicates a full overwrite operation.
