ID of the MJ system user — the account the server runs its own work as.
Canonical definition. Seeded by the baseline on both platforms; do not change it without a
migration.
It lives in a server-side package because it is a server concept — a browser has no system
account and no use for its ID. Both concrete providers (SQL Server and PostgreSQL) depend on
this package and neither depends on the other, so one definition serves both.
Code that needs to ASK whether a user is the system user should call
WellKnownUserSource.Instance.IsSystemUser(user) instead; this constant is for the
implementations that have to know the actual value.
