chore: add license headers to AppLaunchUtils files

Add SPDX license headers to AppLaunchUtils implementation files:
- Add GPL-3.0-or-later license header to applaunchutils.cpp
- Add GPL-3.0-or-later license header to applaunchutils.h
- Add GPL-3.0-or-later license header to applaunchutils_p.h
- Fix code formatting in private header

Log: This ensures proper license compliance and consistent code style.
