Clears the entire ad schedule on the content. Success returns 204 with an empty body.

There is no API to delete a single ad slot by id. To remove one slot, GET the schedule, drop that item from the ads array, and POST the shortened list - or DELETE then POST a fresh schedule.

After delete, List ads on a content returns "ads": [] and "IsDefault": false.

To set a new schedule without an empty step in between, use Create ads on content (POST) directly.
