- Backend DELETE /api/groups/<gid> (admin, own-org enforced via _get_owned_group);
cascades removal of the group's sessions. GroupStore.delete added.
- Training.vue: each group card gets a trash (Trash2 line icon) delete button shown only
to admins (auth.isAdmin); confirm dialog; @click.stop so it doesn't navigate. Card
restructured so the delete button is not inside the clickable router-link.
- test_user_journey: trainee cannot delete (403), admin deletes, group gone (404).
All suites pass. Rebuilt dist.
