Use a panel type condition to differentiate shutter variants in hardware rules

Give a special shutter variant its own panel type so a hardware rule can tell it apart without the shutter design tag.

1. To apply different hardware to a special shutter variant, create a new panel type for that variant.

2. Assign the new panel type in the shutter design.

3. Add a condition on the panel type in the hardware rule.

4. The panel type condition lets the rule distinguish the variant without relying on the shutter design tag, which is unavailable when the rule declaration spans multiple components.
