feat(admin): add server-side pagination and search to list pages

Browse Source 
Companies and Vendors pages now use server-side pagination:
- Moved from client-side to server-side pagination
- Added search with debounced input
- Added status and verification filters
- Added pagination state object (page, per_page, total, pages)
- Added pageNumbers computed with ellipsis support
- Updated templates with search bar and filter dropdowns

Benefits:
- Better performance with large datasets
- Consistent UX across all admin list pages
- Reduced initial page load time
