   TIMESTAMPTZ result rows are serialized as timezone-aware strings in the 
MySQL binary protocol. FE metadata used to advertise them as 
MYSQL_TYPE_DATETIME, so Connector/J decoded the length-encoded string bytes as 
a MySQL datetime binary payload and failed with Invalid length (32) for type 
TIMESTAMP when ResultSet.getString read a server-prepared result.
   
   Change PrimitiveType.toMysqlType() to return MYSQL_TYPE_STRING for 
TIMESTAMPTZ, adjust the field packet length and decimals to string semantics, 
and make the FE local binary result path write TIMESTAMPTZ through the string 
fallback instead of the datetime binary layout. BE serialization already uses 
push_timestamptz -> push_string, so no BE payload change is needed.
   
   Add a field-packet unit test and a regression suite that forces 
ServerPreparedStatement and compares direct ResultSet.getString(ts) with 
CAST(ts AS STRING).
