🔧 refactor(pricing-filters): extract display settings & improve mobile layout (#1365)

* **PricingDisplaySettings.jsx**
  • Extracted display settings (recharge price, currency, ratio toggle) from PricingSidebar
  • Maintains complete styling and functionality as standalone component

* **SelectableButtonGroup.jsx**
  • Added isMobile detection with conditional Col spans
  • Mobile: `span={12}` (2 buttons per row) for better touch experience
  • Desktop: preserved responsive grid `xs={24} sm={24} md={24} lg={12} xl={8}`

* **PricingSidebar.jsx**
  • Updated imports to use new PricingDisplaySettings component
  • Simplified component structure while preserving reset logic

These changes enhance code modularity and provide optimized mobile UX for filter button groups across the pricing interface.
