Add comprehensive configuration and testing for HMAC File Server 3.2

- Introduced configuration files for Docker, Podman, and SystemD deployments.
- Implemented a comprehensive test suite for HMAC validation, file uploads, and network resilience.
- Added debugging scripts for live monitoring of upload issues and service status.
- Created minimal configuration for testing purposes.
- Developed multiple test scripts to validate HMAC calculations and response handling.
- Enhanced upload tests to cover various scenarios including invalid HMAC and unsupported file extensions.
- Improved logging and error analysis capabilities for better diagnostics.
