    test(e2e): close DDL table metadata result set (#38898)
    
    WHAT: Close the ResultSet returned by DatabaseMetaData#getTables when 
DDLE2EIT checks table or view existence.
    
    WHY: The DDL E2E metadata wait loop may poll table state repeatedly, and 
leaking metadata ResultSets can exhaust database cursors.
    
    HOW: Wrap getTables(...) in try-with-resources and keep the existing next() 
result semantics.
