Share hypr_refresh; capture the work laptop's own units

Both laptops run hypr_refresh and their unit files had diverged. The work
laptop's is the refined one — Type=oneshot, which is correct for a script
that exits, a 15s interval with AccuracySec, and a comment explaining the
wallpaper-daemon guard. system76 had Type=simple with Restart=on-failure,
which respawns a oneshot script continuously. Shared version wins.

Three more units existed only on the work laptop and were untracked:
backlight-probe, kanshi and mopidy.
