# During database migrations, we attempt to create a default user. If this user
# already exists (e.g., from a previous deployment or migration), it's not a
# critical error and shouldn't prevent the application from starting. This is
# different from other migration errors which could indicate database schema
# inconsistencies and should cause the startup to fail. This check allows for
# smooth redeployments and container restarts while maintaining data integrity.
