Add a card-based UI layout with consistent spacing and visual hierarchy. The main content and sidebar are now wrapped in styled cards with gaps between them. New theme tokens (card, raised, hover, divider, disabled_fg) provide semantic colors for different surface levels and states. Create ui.rs module with helper functions (card_style, divider_h, section_header, priority_badge) to keep styling consistent across views.
