Description
📝 Description of the feature
Design question: do we want to sync the UI state to the server, so it can stay up to date, or do we want this to remain client-owned entirely?
Today, at save_state time, the UI state, like the rest of the state, is retrieved by the server through a client round trip. Do we want to continue this pattern for the UI state, which is independent of the VTK pipeline? Or do we want to use a sync-back pattern like the camera, and store the UI state metadata on the server, so that save_state doesn't require a client round trip, and so that a refresh or reconnect will preserve the UI state as well as the VTK pipeline?
If we want to keep the UI state purely client-side, there is no work here.
If we want it to be synced back to the server, then the TheiaUIState (panel collapsed/expanded, active tab index, dark/light theme) flows through the same save/load paths as camera and per-part state.
More details to be added in backlog grooming.
Acceptance Criteria
- No in-visualizer behavior changes.
- Refresh behavior depends on the decision that gates the rest of this user story.
