Support a 3rd primary key (named extra field) through mysql-query-service

editor related: creature-text (and any with 3 Primary Keys)
the goal is to support 3 primary keys at the same time by the mysql-query-service using the "extra id" field implemented here https://github.com/azerothcore/Keira3/pull/3038

Expected behavior in creature-text:
a user should be able to manage 2 rows with the same GroupID but different IDs

Could be related (or the same) to https://github.com/azerothcore/Keira3/issues/2242

Start by reviewing the extra-id implementation in Keira3 pull request 3038 and the related issue 2242, then trace how creature-text is handled through mysql-query-service. Done means users can manage two rows with the same GroupID when their IDs differ, while supporting the third primary key for other affected tables.
