Add explicit accessCheck(TRUE/FALSE) to content entity queries

The upgrade status module is still complaining about this in some places, but not all. A bug in https://www.drupal.org/project/upgrade_status → perhaps?

In the latest versions, functions continue to appear in the code without explicit accessCheck(TRUE/FALSE) to content entity queries.

For example in the function "tmgmt_entity_delete" in the code file "tmgmt.module". This case is really worrying because it causes errors in the removal of any content, leaving Drupal 10 websites completely inoperative.
