fix(tests): Fix flaky test_gracefully_handles_missing_user ID collision#108991
Conversation
Use a large user ID (2147483647) instead of 999 to ensure the user doesn't exist in the test database. With sequential auto-increment IDs, user ID 999 can be created by other tests running before this one, causing the missing-user code path to be bypassed. Fixes #108980
