feat: adds String implementation for ApiError and FileWrapper

[haseeb-mhr]

What

This PR implements String() methods for the ApiError and FileWrapper structs. By adding these methods, the structs now support customizable and readable string representations, allowing developers to print or log their content in a human-friendly format.

Why

Previously, printing or logging ApiError and FileWrapper resulted in raw struct output, which could be difficult to interpret and debug, especially when dealing with complex or nested data. By implementing String() methods:

• Developers gain clearer, formatted representations of these structs, improving debugging and logging capabilities.
• It enhances usability by aligning with Go's standard practices for pretty-printing objects.
• This provides better insights into the contents of ApiError and FileWrapper without requiring manual struct formatting or additional debugging tools.
