Root cause: JPA defaults an entity's table name to its simple name. `Order` the Java class
becomes `order` the table name, and ORDER is a reserved word in H2 (and in the SQL
standard, and in Postgres, and in MySQL) because of the ORDER BY clause. Hibernate's
schema-update path logs this as an error and carries on, which is worse than failing fast
-- the table partially/never exists and every INSERT against it fails later with its own,
less obvious error. Fixed with @Table(name = "orders") on the entity.
