Polish pass: micro-interactions on admin and storefront pages

Admin design system:
- AdminCard: hover shadow elevation
- AdminTable: enhanced empty state, row hover
- AdminBadge: tracking-wide typography
- AdminButton: active scale press feedback
- AdminFormElements: input transitions
- AdminFilterBar: search input polish
- PageHeader: icon hover scale, chevron separator
- AdminToggle: glow effect, thumb shadow
- AdminEmptyState: icon hover, spacing
- AdminPagination: active solid bg, ellipsis

Storefronts (tuxedo + indian-river-direct):
- Button hover lifts (-translate-y-0.5)
- Shadow elevations on hover
- Button press feedback
- Consistent timing (duration-200)
- Product card image zoom
- FAQ empty state fix
