refactor: improve network interface validation

Add context parameter to validInterfacesMap for better error handling and
logging. Move Windows-specific network adapter validation logic to the
ctrld package. Key changes include:

- Add context parameter to validInterfacesMap across all platforms
- Move Windows validInterfaces to ctrld.ValidInterfaces
- Improve error handling for virtual interface detection on Linux
- Update all callers to pass appropriate context

This change improves error reporting and makes the interface validation
code more maintainable across different platforms.
