[pim/kalarm] src: Use KCalendarCore::MimeData for DnD operations

Git commit 9da28b82b60c511cc4463012541d56ec777b5de9 by Volker Krause.
Committed on 19/07/2026 at 07:07.
Pushed by vkrause into branch 'master'.

Use KCalendarCore::MimeData for DnD operations

Once we depend on KF 6.29 this will remove the dependency on kcalendarutils
here entirely.
