fix: resolve InputStream to String conversion inefficiencies

Browse source

Refactored multiple methods for converting InputStream to String for improved performance and memory efficiency.

- Simplified small file handling using Scanner.

Addresses performance issues and ensures better handling of edge cases in InputStream processing.
