* perf: utilize smartstring for string handling

- Updated various modules to replace standard String with smartstring::alias::String for improved performance and memory efficiency.
- Adjusted string manipulations and conversions throughout the codebase to ensure compatibility with the new smartstring type.
- Enhanced readability and maintainability by using `.into()` for conversions where applicable.
- Ensured that all instances of string handling in configuration, logging, and network management leverage the benefits of smartstring.

* fix: replace wrap_err with stringify_err for better error handling in UWP tool invocation

* refactor: update import path for StringifyErr and adjust string handling in sysopt

* fix: correct import path for CmdResult in UWP module

* fix: update argument type for execute_sysproxy_command to use std::string::String

* fix: add missing CmdResult import in UWP platform module
