Fix: unify temporal tiling toggle and align UI with backend

- Removed redundant UseTemporalTiling property from TiledVAECardViewModel
- Consolidated temporal tiling logic into UseCustomTemporalTiling
- Updated TiledVAECard.axaml bindings to use UseCustomTemporalTiling
- Ensured temporal controls visibility and backend behavior remain consistent
