When a schema with zero columns was passed to ExecuteBulkIngest, the expression `MySQLMaxPlaceholders / numCols` caused a division-by-zero panic. Schemas with more than 65,535 columns would silently produce a batch size of zero. Add explicit early-return errors for both cases, consistent with how the Dolt driver handles the same condition. Move validation ahead of the `createTableIfNeeded` call so no database interaction occurs for invalid inputs.
