fix(viewer): drop the EntityRef-keyed selection half in clearAllModels too

[BIMvoice]

Summary

• clearAllModels()'s all-models-cleared teardown scope cleared only the global-id half of selection state (selectedEntityId/selectedEntityIds/selectedStoreys). The EntityRef-keyed half (selectedEntity/selectedEntities/selectedEntitiesSet/selectedModelId/activeStorey) survived, still naming models clearAllModels() had just removed.
• resetViewerState() already clears both halves, so the asymmetry only showed on a path that calls clearAllModels() without it — GeoreferencingPanel.tsx's reloadModelsForAlignment, which reloads models after clearAllModels() alone.
• Fix: since clearAllModels removes every model, there is no surviving federated sibling to preserve a selection for (unlike the single-model model-removed scope, which filters by modelId), so the all-models-cleared arm now clears both halves unconditionally — same shape session-reset already used for this slice.
• Updated PINNED_ALL_MODELS_CLEARED_KEYS in teardown-registry.test.ts to include the five newly-emitted keys.

Refs #3348.

Test plan

• apps/viewer/src/store/clearAllModels-selection-stale.test.ts — new test, confirmed RED against the pre-fix arm (selectedEntity/selectedEntities/selectedEntitiesSet/selectedModelId/activeStorey all survived clearAllModels()), GREEN after the fix.
• teardown-registry.test.ts, selectionSlice.test.ts, clearAllModels-overlay-stale.test.ts, removeModel-*.test.ts, resetViewerState.*.test.ts, teardown.idempotence.test.ts, *.solid-teardown.test.ts — 88/88 passing.
• tsc --noEmit clean for apps/viewer.
• node scripts/check-module-size.mjs exits 0.
