Add icon rendering and list scroll gesture support

Browse Source 
Implement orientation-aware icon rendering using freeink::Icon format that applies rotation transforms per-pixel. Add wasListScroll helper for touch-based list navigation with swipe gestures. Switch vertical centering from x-height to cap-height for better visual alignment with capital-led UI labels.
