🐛 fix: group-ratio display & deduplicate price logic in model-pricing views

Summary
• Ensure “Group Ratio” shows correctly when “All” groups are selected.
• Eliminate redundant price calculations in both card and table views.

Details
1. PricingCardView.jsx
   • Removed obsolete renderPriceInfo function.
   • Calculate priceData once per model and reuse for header price string and footer ratio block.
   • Display priceData.usedGroupRatio as the group ratio fallback.

2. PricingTableColumns.js
   • Introduced WeakMap-based cache (getPriceData) to compute priceData only once per row.
   • Updated ratioColumn & priceColumn to reuse cached priceData.
   • Now displays priceData.usedGroupRatio, preventing empty cells for “All” group.

Benefits
• Correct visual output for group ratio across all views.
• Reduced duplicate calculations, improving render performance.
• Removed dead code, keeping components clean and maintainable.
