Replace the raw flavor slug in the GPU Instances list with the product name
("<product> x <count>") plus an info-icon popover that breaks the spec down by
category (GPU / CPU / Memory / Disk): per-card VRAM, whole-instance CPU/RAM,
system / ephemeral / persistent disks (persistent size resolved from the
referenced PV). Extract the cell into a shared InstanceTypeCell and centralize
memory formatting in formatMemoryDisplay so the GPU Instances list and the
Usage tab render identical sizes.
In the platform-admin "all organizations" view, add an organization picker
(the CreateOrgScopeField slot) to the SSH public key, storage type,
storage, GPU instance and instance-template create forms, placed below the
name / display-name fields. Drop the hidden owner field and let the owner
derive from the request context, matching the model-route form.
For GPU instances, scope the instance-type list to clusters the chosen org
owns (client-side, by cluster owner) so an instance can't be scheduled onto
another org's cluster; when the org owns none, show "no instance type
available" and clear the selection, cluster and CPU/memory fields. Instance
templates gain a Global level (NULL owner) and an owner tag on the card.
