fix(stripe): add error handling and resilience to subscription operations

- Record refunds immediately before cancellation to prevent retry issues if cancel fails
- Wrap Stripe API calls in try-catch for refunds and quantity reverts with internal notifications
- Add null check in Team.subscriptionEnded() to prevent NPE when subscription doesn't exist
- Fix control flow bug in StripeProcessJob (add missing break statement)
- Cap dynamic server limit with MAX_SERVER_LIMIT in subscription updates
- Add comprehensive tests for refund failures, event handling, and null safety
