Enhanced OrgIcon

[Rajesh-Nagarajan-11]

Notes for Reviewers

• Currently, the fill prop of the icon is mainly applied to the windows and doors
• The fill color should instead be applied to the central/main building to establish clear visual focus.
• The left and right sections of the building should use secondary colors to maintain hierarchy. ( secondaryFill )
• An additional prop like windowFill (or similar) should be used exclusively for windows, allowing independent control without affecting the main structure.

This separation improves visual clarity, theming flexibility, and consistency across icons.
