fix: Mark strings for translation

Mark strings that previously were not marked for translation, making the
UI show text partially in English and partially on another language on
some dialogs.

Changed shared dialog classes to assume instance variables holds already
localized strings, no need to further call gettext functions on them.
This means classes that inherit these shared ones should no longer use
'N_(...)', but instead '_(...)'.
