this is all modification groups for all notStashedNodes for all root networks.
Then we should rename stashedModificationGroupUuids to notStashedNodesModificationGroupsUuids
the filtering between stashed modification or not stashed ones is not done here and there is no meaning of stashed or not stashed groups in the system.

.map(NetworkModificationNodeInfoEntity::getModificationGroupUuid)
.toList();
networkModificationService.deleteStashedModificationsGroups(stashedModificationGroupUuids);

Does a stashed modification exists in a group which contain a non stashed modification in a non stashed node ?
I see that when we stash a node, we call deleteStashedModifications. it's not clear for me i will investigate.

I think it's ambiguous. Some network modifications should remain.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Run study-wide stashed-element cleanup once, outside the root-network loop.

invalidateStudy processes every root-network ID, but deleteAllStashedElements(studyUuid) reads all nodes for the study and sends a remote deletion request for all non-stashed groups on each invocation. If a later invocation fails, the per-root catch runs before invalidateStudyRootNetwork, so that root network remains LOADED and is not invalidated. Move the cleanup before the loop, handle its exception separately, and keep the per-root error handling for root-network invalidation.

line 409, Update invalidateStudy so deleteAllStashedElements(studyUuid) runs
once before iterating root-network IDs, with its exception handled separately;
retain per-root error handling and invalidateStudyRootNetwork processing inside
the loop.
