[BUG] Subscription not recognized: account shows Free plan after Max plan payment (affects Claude Code, browser, Windows & macOS)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

I paid for the Max plan and have valid invoices and receipts confirming the payment.
However, my account is still treated as Free plan.

This issue is not limited to Claude Code:

• Claude Code CLI shows Free plan
• Browser (web app) also shows Free plan
• Authentication/onboarding flow repeats
• API key (ANTHROPIC_API_KEY) is not available because the account is not recognized as paid

This happens across platforms:

• Windows
• macOS
• Browser

This indicates an account-level or billing sync issue, not an OS-specific or local installation problem.

What Should Happen?

After a successful Max plan payment, the account should immediately be upgraded and recognized as Max plan:

• Claude Code should reflect the paid plan
• Browser UI should show the correct subscription
• API access should be enabled
• Onboarding should not repeat
• Authentication state should persist correctly

Error Messages/Logs

No explicit error messages.

Symptoms:
- Account always appears as Free plan
- ANTHROPIC_API_KEY is unavailable
- Claude Code requires authorization every time
- Paid features are inaccessible

Steps to Reproduce

1. Purchase the Max plan (payment is successful, invoices and receipts are generated)
2. Log into the Claude web interface
3. Observe that the account still shows Free plan
4. Install and run Claude Code CLI
5. Attempt to authenticate
6. Observe that:

• Account is treated as Free
