## PR-Codex overview
This PR focuses on updating the `ExploreCategoryPage` component in the `page.tsx` file to utilize a new client obtained from `getThirdwebClient` instead of passing it as a prop. This change simplifies the component's props and enhances its internal logic.

### Detailed summary
- Removed the `client` prop from `ExploreCategoryPageProps`.
- Introduced `const client = getThirdwebClient(undefined);` to obtain the client internally.
- Updated the `client` prop of the `ContractCard` component to use the newly defined `client` variable instead of `props.client`.
