fix: make nested links clickable in recipe cards

Use the card wrapper pattern with absolute positioned main link and elevated z-index for nested links.
This maintains proper HTML semantics (no nested <a> tags) while allowing category, icon, and tag links to be clickable.

- Replace outer <a> wrapper with <div>
- Add invisible overlay link for main card click area (z-index: 1)
- Elevate nested links (category, tags, icon) with z-index: 10
- Maintain all existing hover effects and accessibility
- Keep semantic HTML structure without nesting <a> tags
