[FIX] mail_forward: Correctly Render Actions with Components

This fix ensures that actions using callComponent are rendered properly.

Previously:

The first two actions were always rendered and invoked their respective components.
Remaining actions were only triggered when clicking a DropdownItem, without invoking the component.
Solution:
To address this inconsistency, we add the action to the quick actions and ensure that three items are displayed instead of two.

Question:
Could this behavior be considered an Odoo bug? See the related code here:
