feat: transform catalog to modern grid layout with compact product cards

- Transform Card.vue from horizontal to vertical compact design
- Reduce card height with fixed image max-height (160-240px responsive)
- Center all text content (product name, prices, actions)
- Style product name with semibold font-weight, 2-line ellipsis
- Redesign price labels: subtle gray uppercase for labels, bold primary for values
- Style quantity controls: tonal icon buttons with smooth animations
- Redesign input field: solo-filled variant, compact density, subtle shadow
- Transform catalog.vue list layout to responsive grid (v-row/v-col)
- Implement responsive columns: 1 col mobile, 2 cols tablet, 3 cols desktop
- Clean up obsolete .catalog-item styles, use native Vuetify grid spacing
- Add hover effects: translateY(-6px), scale(1.08) on image, border highlight
- Add footer background (#fafafa) for visual separation
- Optimize breakpoints: 6 responsive sizes (374px, 559px, 959px, 1280px, 1920px)
- Result: Professional, compact, balanced e-commerce catalog design
