refactor(ui): redesign mobile card layout in Table component

- replace fixed column-slice layout with mobileHidden filter for flexible column visibility
- render primary column as prominent header with semantic styling
- display remaining columns in a responsive 2-column dl grid with label/value pairs
- update MobileSkeletonCard to reflect new grid structure based on visible column count
