fix(sqlite): declare _tenant as INT(11) UNSIGNED for schema parity

testSchemaAttributes expects the shared-tables _tenant column to report
dataType=int and columnType in [int unsigned, int(11) unsigned], to
match what MariaDB's INFORMATION_SCHEMA returns. The previous INTEGER
declaration came back from PRAGMA as 'integer', which parseSqliteColumnType
mapped to dataType=integer. Declaring the column with the quoted MariaDB
shape makes PRAGMA echo it back verbatim — INTEGER affinity is preserved
because the type still contains "INT".
