• If you delete a scheduleEntry from the Activity view, the frontend breaks.
• If you add a ScheduleEntry to an activity, a new activity is created, instead of adding a scheduleEntry to the activity.

Reverted with

• Revert "feat: Edit schedule entries from activity view" #4967
  Probably fixed with
• Remove unnecessary function calls and this.api bindings in router.js #5025

Must be tested again with
