[Bug]: Feedback Cards Alignment and Responsive Layout Issues

### 📋 Description
The feedback cards on the main page have alignment and responsiveness issues. The cards are not properly aligned, and the layout breaks or looks inconsistent on different screen sizes, particularly on mobile devices.

### 🔍 Current Behavior

- Card layout doesn't adapt well to different screen sizes
- On mobile/tablet, cards may overlap or have awkward spacing
- Vote buttons and score display may not align properly within cards
- Company logos and sentiment badges positioning is inconsistent

### ✅ Expected Behavior
- Feedback cards should be consistently aligned in a responsive grid
- Cards should maintain equal heights and spacing
- On mobile devices, cards should stack properly with appropriate padding
- All card elements (logo, company name, sentiment badge, feedback text, vote controls) should be properly aligned
- Grid should adapt smoothly from desktop (3-4 columns) to tablet (2 columns) to mobile (1 column)
