Add multi-OS support for Linux package mirror configuration

- Import updateLinuxMirrorFile function to support Debian, Ubuntu, and Alpine
- Add OS detection logic (detectOS, getOSReleaseInfo, isDebian, isUbuntu, isAlpine)
- Add mirror domain extraction and replacement functions
- Update SystemService.updateLinuxMirror to use new multi-OS implementation
- Save config only if mirror update succeeds (hasError flag)
- Support different source files: /etc/apt/sources.list.d for Debian/Ubuntu, /etc/apk/repositories for Alpine
