fix: make cookbook cards square and more compact

Changes to cookbook cards:
- Set aspect-ratio: 1 / 1 on cards to maintain square shape
- Changed cover height from 16:9 ratio to 60% fixed height
- Hidden description to reduce card height
- Reduced padding from 1.25rem to 0.75rem
- Reduced title font from 1.3rem to 1rem
- Reduced recipe count font from 0.9rem to 0.8rem

This makes cookbook cards display as squares similar to recipe cards,
preventing them from becoming too tall.
