feat: Add switch to org button on plan usage screen

[charlesvien]

Problem

PlanUsageSettings detected hasBetterPlanElsewhere and showed a callout but offered no way to actually switch to the org with the better plan. The page also called client.switchOrganization directly from the renderer, bypassing the main-process auth service.

Changes

1. Add a "Switch to {org}" button to the hasBetterPlanElsewhere callout
2. Route every renderer org switch through useSwitchOrgMutation so AuthService.switchOrg is the single canonical path
3. Refetch the seat with autoProvision: true after the switch so the Pro card reflects the new active org
4. Show a red error callout when the switch fails, with a ?? "Pro org" fallback when the API omits the org name

How did you test this?

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.
