Previously gated to tenant-owned rows (tenant_id != null), which made
seed-from-catalog rows uneditable since they default to platform scope
on the backend. The backend doesn't enforce extra ownership rules on
update/delete either, so the gate was a UI overreach.
Buttons now appear on every row. Tooltips clarify when a row is a
platform default so the operator knows the change applies broadly.
