Implement Resource Cart for Client Selection

[tenvoltz]

Description:
The public view should allow clients to select multiple resources and add them to a cart. This feature will enable users to easily collect and review selected resources before taking further action, such as requesting updates or sharing the list.

Checklist:

• Implement checkboxes or "Add to Cart" buttons on each resource listing for users to select resources.
• Create a cart component where selected resources are stored temporarily.
• Ensure that users can view the contents of their cart and remove items if needed.
• Provide an option for users to finalize their cart (e.g., export to PDF)
• Ensure that the cart persists across page reloads or navigations within the session.
• Implement a UI indicator (e.g., cart icon with item count) to show how many resources are currently in the cart.
• Test the cart functionality to ensure it handles multiple selections and updates correctly.
• Ensure the cart is responsive and easy to use on both mobile and desktop devices.
• Document the cart implementation for future reference or enhancements.
