Records a one-time Pro upgrade charge for the case and returns status: 'processing'; the case becomes Pro once the invoice is paid, or right away when the plan already includes Pro, and repeating the request does not charge again. Requires a member role or above in the organization, owner or admin access to the case and an active plan (403 otherwise); not available to opposing counsel. Returns 403 when case billing is not enabled for the organization or the case belongs to a different organization than the organization header, and 409 when the case is already Pro.
