[BUG] Plan upgrade payment fails — PaymentIntent voided immediately with `void_invoice` before confirm can complete

What's Wrong?

When attempting to upgrade from the Pro ($20/month) plan to the Max ($100/month)
plan on claude.ai, the payment confirmation step fails immediately with no
actionable error — just a generic failure message.

Multiple Visa cards from two different banks were attempted. All fail with the
same error, confirming this is NOT a card or bank issue.

What Should Happen?

Upgrade from Pro → Max completes successfully. PaymentIntent remains in a
confirmable state until the user finishes checkout.

## Root Cause (from #55982)

As documented in #55982, the underlying Stripe error is:


{
  "error": {
    "code": "payment_intent_unexpected_state",
    "type": "invalid_request_error",
    "message": "This PaymentIntent's mandate_data could not be updated 
    because it has a status of canceled.",
    "payment_intent": {
      "status": "canceled",
      "cancellation_reason": "void_invoice"
    }
  }
}

Steps to Reproduce

1. Log into claude.ai on an active Pro ($20/month) plan
2. Navigate to Settings → Billing
3. Initiate upgrade to Max ($100/month) plan
4. Enter card details and proceed through confirmation
5. Observe failure — payment never goes through

Additional Information

This issue is still actively occurring as of May 2026. The $20/month Pro charge
succeeds on the same cards, confirming the cards themselves are valid. The
failure is specific to the upgrade flow.
