feat: Integrate a responsive pagination component for data tables

[AlAfiz]

Description

As we add more tokens and pools, our data tables will become too long to display on a single page.
We need a reusable <Pagination /> UI component that can be placed at the bottom of any table.
It should feature "Previous" and "Next" buttons, along with clickable page numbers.
For now, it only needs to manage its own internal visual state, not actual data slicing.

Requirements

• Create components/ui/Pagination.tsx.
• Accept currentPage, totalPages, and onPageChange as props.
• Render a styled "Previous" button that is disabled if currentPage === 1.
• Render a styled "Next" button that is disabled if currentPage === totalPages.
• Add the component to the bottom of the /pools overview table.
