Renaming a root network tag rewrites the applicabilities of the shared modifications of the study, which other studies use too: it now requires the write permission on each of them.

Adds GET /studies/{studyUuid}/network-modifications/references/exists, telling whether a study holds shared modifications, for the front to warn before a rename.

Goes with gridsuite/network-modification-server#901 and gridsuite/gridstudy-app#4209.

Renaming a tag rewrites the applicabilities of the shared modifications of the
study, so it now requires the write permission on each of them. Also exposes
whether a study holds shared modifications, for the front to warn beforehand.

Walkthrough

The change adds shared modification reference lookup, enforces write permission for root-network tag renames affecting those modifications, and adds an endpoint that reports whether a study has shared modification references.

Verify the mocked exchange before verifyNoMoreInteractions.

The non-empty call invokes restTemplate.exchange. Mockito counts this invocation as an interaction even when it is stubbed. verifyNoMoreInteractions(restTemplate) therefore fails.

Add an explicit verification before this assertion.

Proposed fix
         assertThat(networkModificationService.getReferencedModifications(List.of(groupUuid))).containsExactly(sharedModificationUuid);
         assertThat(networkModificationService.getReferencedModifications(List.of())).isEmpty();
+        verify(restTemplate).exchange(expectedUrl, HttpMethod.GET, null, new ParameterizedTypeReference<List<UUID>>() { });
         verifyNoMoreInteractions(restTemplate);
