fix: add domain to translatable strings

This allows plasma to load translations from `/usr/share/locale` when
the plugin is installed system wide.

Also from Plasma 6.5.6 and later when they are included with the plugin
in `contents/locale/$language/LC_MESSAGES/$domain.mo`, which is needed
for KDE Store or non system-wide installs.
