treewide: read commit description

What changed here was:
- I updated the lock file
- I added ZNC to my services
- I moved my services to a new directory
- I renamed my user to arturm
- I renamed my system to cityseventeen
- I moved to en_US.UTF-8
- I switched to using Rose Pine
- I added a Mako option
- Some refactoring where it was needed

These are all changes I forgot to commit, I had intentions
of commiting them but I didn't until now. Oops!
