Implement Pagination for Asset Retrieval

[wjuniorbh92]

Summary:
This PR introduces pagination to the asset retrieval functionality in our system. It modifies the AssetRepo to include a GetPaginated method, allowing the API to fetch assets in a paginated format. This enhancement aims to improve performance and usability, especially when dealing with a large number of assets.

Key Changes:

1. Pagination in Asset Retrieval:

   • Added GetPaginated method to AssetRepo which fetches assets based on the provided page number and limit per page.
   • Implemented SQL LIMIT and OFFSET clauses in the query to facilitate pagination.
   • Calculated the offset based on the current page number and the number of records per page.

2. API Endpoint Adjustment:

   • Modified the /assets endpoint to support pagination parameters: page and limit.
   • Ensured backward compatibility - when pagination parameters are not provided, the endpoint returns all assets.

3. Error Handling and Edge Cases:

   • Added checks for edge cases, such as negative page numbers or limits.
   • Included comprehensive error handling to capture and respond to any issues during the database query execution.
