Feature Request: Notify customers when webspace quota is full

[TCRserver]

Please add an automatic email notification when a customer’s webspace quota reaches a defined threshold (e.g. 80%, 90%, 100%).
Currently, LiveConfig sends quota warnings only for mailboxes, not for the webspace quota.

We've been having repeated problems lately with WordPress backups cluttering the space, and the customer doesn't notice. It's not a specific LiveConfig issue, but it reduces the number of support tickets and offers the customer more quality.
