📱 feat(pricing-header): show only search/copy/filter on mobile; hide vendor intro

- Mobile (isMobile=true): render SearchActions (search, copy, filter) only; hide vendor intro card
- Keep PricingFilterModal available on mobile for filtering
- Desktop/Non-mobile: unchanged behavior (vendor intro remains visible)
- Improves small-screen UX by reducing visual clutter and prioritizing primary actions

Files:
- web/src/components/table/model-pricing/layout/header/PricingTopSection.jsx

Notes:
- Added `SearchActions` import and conditional rendering
- No breaking changes; no styling changes required
