Problem
Choosing a different token-group in the pricing sidebar only updated the filter but did **not** refresh the displayed group ratio in both the Table (`@table/`) and Card (`@card/`) views. The callback used by the sidebar changed `filterGroup` yet left `selectedGroup` untouched, so ratio columns/cards kept showing the previous value.

Solution
• `PricingSidebar.jsx`
  – Accept new prop `handleGroupClick` (from `useModelPricingData`).
  – Forward this callback to `PricingGroups` (`setFilterGroup={handleGroupClick}`) while retaining `setFilterGroup` for reset logic.
  – Keeps both `filterGroup` filtering and `selectedGroup` state in sync via the single unified handler.

Result
Switching groups in the sidebar now simultaneously updates:
1. the model list filtering, and
2. the ratio information shown in both pricing Table and Card views.

No UI/UX regression; linter passes.
