Ole-Morten Duesund 3341e9a818 fix: preserve systemd enable/disable state on package upgrade
The preremove script was unconditionally stopping and disabling the
service, which meant upgrades (dpkg -i new.deb) would disable the
service. Users had to manually re-enable after every upgrade.

Now:
- preremove: only stop+disable on actual removal (not upgrade)
  Checks $1 for "remove"/"purge" (deb) or "0" (rpm)
- postinstall: restart the service on upgrade if it was running,
  preserving enable/disable state. Only shows first-install
  instructions on initial install.

Tested with shellcheck.
