fix: Address PR feedback - rename test file and follow coding style

- Rename testtildeexpansion.cpp to testutilsfs.cpp as requested
- Follow qBittorrent coding style with proper copyright header
- Add missing Q_DISABLE_COPY_MOVE directive and const methods
- Update CMakeLists.txt to reference correct test filename
- All 17 tests pass including tilde expansion functionality
