MINIFICPP-2181 Use systemd service management on Linux

[szaszm]

I generated small parts of this PR with GitHub Copilot. I believe all of the generated snippets are trivial enough to not be copyrightable in their own right, and I would have written the same myself. For this reason, I believe that I own the copyright for the whole code, and it can be licensed under the Apache License 2.0.

In more details: when I started a line, the AI prediction could analyze the surroundings and complete console messages and file paths in a similar manner to what was already written, but it didn't generate any non-trivial parts of any specific feature.
