🐛 Standardize carousel container dimensions

[sjproctor]

Story: [i249] Standardize featured works carousel container dimensions in logged-out view of Neutral Theme

Ref:

• Carousel isn't fixed size like it used to be notch8/palni_palci_knapsack#249

Expected Behavior Before Changes

• Carousel container resized based on image dimensions causing page layout shifts
• Image transitions were jumpy

Video: Before changes

Expected Behavior After Changes

• Set container height and standard image size
• Smooth transition during carousel changes

Video: After changes

Notes

• adds a fixed height container (400px) to maintain consistent carousel size even when images have different dimensions
• adds object-fit and transition properties to prevent image stretching during slide transitions
• favors Bootstrap classes where possible
• improves image positioning and aspect ratio handling in carousel items
