another.im (and any UnifiedPush app) is woken by its server for each
message only while a distributor runs on the session bus; GNOME has
none, so the app reported "no UnifiedPush distributor" and missed
messages once quit. KUnifiedPush's distributor needs no Plasma and
uses KDE's ntfy server by default.
Its unit ships in share/systemd/user, which systemd.packages does not
read, so the user service is written out here as the package's own
(26.04), started with the graphical session.
