Stripe sends webhook events asynchronously. A customer.subscription.created may arrive before customer.created, causing DB foreign key errors.

In the subscription lifecycle webhook handler (from PR #776), add a guard before processing subscription events
For subscription events: verify the customer exists in the local DB before processing
If customer not found: return 200 (acknowledge to Stripe) but queue the event for retry in 30s
Implement a simple in-memory retry queue with max 3 attempts
After 3 failures, log an error with full event payload for manual investigation
Add test: send subscription event with no customer, verify it's queued not rejected

Acceptance: Out-of-order Stripe events don't cause 500 errors. Tests pass.
