No coins refunded after edit or delete

[pivilartisant]

Before launching, we need to integrate on cli and frontend the coins refund implementing the withdraw function from the SC.

This should be pretty straight forward for the delete, but what about the edit ? technically since users are delete from storage, they should get refunded or should they request to be refunded ? How can we optimize this in the edit flow so users do not pay for what is already payed for ?
