Replace mailbox quota

Set a mailbox quota in megabytes on a cPanel-backed shared-hosting account. {address} accepts either the literal mailbox address or the mail_... ID from the mailbox list. Send quotaMb: 0 for unlimited where the platform allows it. If this returns account_not_eligible_cpanel, use the control panel SSO link manually or contact support to migrate the account to a newer cPanel-backed plan.
