feat: add WSL and Docker support for file location opening

- Add WSL detection and Windows path conversion using wslpath
- Add Docker/Kubernetes detection via /.dockerenv and /proc/1/cgroup
- Implement clipboard fallback for containerized environments
- Update open_file_location handler to detect WSL/Docker before POSIX
- Update open_settings_location handler with same detection logic
- Add clipboard API integration with graceful fallback in frontend
- Add translations for clipboard feature across all 10 languages
- Add unit tests for _is_wsl(), _is_docker(), and _wsl_to_windows_path()

Fixes file manager opening failures in WSL and Docker environments.
