API delete endpoint is silently failing

[nickdos]

In previous versions, an entity could be deleted via the API using /ws/dataResource/{dataResourceUid} using a HTTP DELETE method.

When triggered, a 200 response returns with content deleted title-of-collectory-entry. However the entity is not deleted and can be viewed by its public URL after this.

The code responsible does not send flush: true which used to be optional but is now a mandatory command.

• Add flush: true to the delete command and search for other cases where DB save/delete are also not sending the flush command.

In earlier Grails versions (pre-GORM 7), transactions were automatically flushed at the end of controller actions. In Grails 6.0.0 (which uses GORM 8.x), this auto-flush behavior was disabled by default for better performance and more explicit transaction control.

Needs testing still
