Calendar: Restore events that were deleted *could have*

[FelixSchmandt]

• As service staff I want to be able to restore events that were deleted.
• At any time
• So that all info pertaining to an event does not have to be reentered in case the event was deleted by accident

One way to implement a way to delete and restore events could be to work with a "recycle bin":

• Entries in the database for events are not actually deleted, but marked as "in the recycle bin".
• Such entries marked as "in the recycle bin" will not be displayed in the normal views, but can be viewed and restored in the recycle bin.
• Restoring an event from the recycle bin will remove the mark as "in the recycle bin".

Question: What happens, when another event has been created in the same timeslot in the same room and a deleted event in the same timeslot in the same room is restored? --> There will be no automated consistency/ capacity checking, which could lead to errors, right?
