What T-Rex did

• Reviewed the changed plan usage flow around organization switching and billing links.
• Verified that same-org billing links skip the switch path before opening billing.
• Verified that a successful callout switch refetches the seat with autoProvision: true.
• Checked the switch mutation state shared by the callout and billing buttons.

   Block duplicate switches

   The billing Open button is disabled only when billingUrl is missing, so it can still be clicked while an organization switch is already in flight. That starts another switchOrg mutation while the first one is resetting session state and refreshing auth-scoped queries. Disable the billing buttons while switchOrgMutation.isPending, matching the guard used by the existing project switcher, to avoid concurrent session resets.
