Reworked the repeat schedule wizard (#4850)

* Simplified design and concept
* Sticking closer to the original schedule
* Added option to keep gap days (front and back)
* Added option to use originally planned dates
* Removed options to insert rest days or spread same day activities
* Improved source range preselection
