fix(db): keep Integer-mapped wiki flag columns as SMALLINT in the PostgreSQL-family tree

The blanket SMALLINT->BOOLEAN flag-column conversion over-reached: six wiki
columns map to Integer (1/0) entity fields, not Boolean. On vanilla PostgreSQL,
reading a BOOLEAN into a JDBC int throws 'Bad value for type int : f', breaking
every wiki KB list / SSE chat. Revert only those six back to SMALLINT (V133/V134/
V135/V136/V146 in the PostgreSQL-family tree) with guard comments; genuine
Boolean-entity columns stay BOOLEAN.
