Refactor API Response Structure to Use Inline Data Field

- Updated the APIResponse struct to change the Data field to use inline JSON representation, enhancing the response format.
- Removed the Meta field from the SuccessWithMeta function, simplifying the success response handling.
- This change improves the clarity and consistency of API responses, aligning with best practices for response structures.
