Fix is_closed state and position for DynamicPergola covers in Overkiz

[iMicknl]

Proposed change

The DynamicPergola widget uses core:OpenClosedState and core:ClosureState, unlike bioclimatic pergolas that use core:SlatsOpenClosedState. Without a widget-level override, the UIClass.PERGOLA fallback looked for slats state that doesn't exist on this device, causing the cover to report unknown state.

Fixes #170812

Pull request overview

This PR fixes Overkiz pergola cover state/position handling by updating the Pergola UIClass defaults to use core:OpenClosedState + core:ClosureState, while adding a widget-specific override to preserve the existing bioclimatic pergola (slats/tilt) behavior.

Changes:

• Update UIClass.PERGOLA mapping to use core:OpenClosedState for is_closed and core:ClosureState for position.
• Add a UIWidget.BIOCLIMATIC_PERGOLA override to keep slats open/closed + orientation (tilt-only) support.
• Extend Overkiz test fixtures and service/snapshot coverage for DynamicPergola and PergolaHorizontalAwning.
