Corrige docs/11: query de validação abreviada causava ORA-00903

O capítulo 11 mostrava a query de checkpoint com placeholders '/* ... */'
só ilustrativos, mas com botão 'Copiar' ao lado — usuário copiou e
rodou direto, e 'FROM (/* ver script completo */)' virou subquery
vazia (ORA-00903 invalid table name). Substitui pela query real e
completa, idêntica à de sql/03_v2_ddl_schema_evolution.sql. Os ALTER
TABLE em si rodaram OK, não foi um problema do DDL.
