fix(video3d): drop pending layer bind when the explorer closes

[IAnMove]

Problem

#229 merged without clearing pendingBindRef / reassignId when the layer explorer closes. Cancel/Escape could leave a capture that a later hidden file input applies to the old layer.

Behavior

Explorer onClose drops the pending capture and reassign id.

Base

origin/development b2aee310 (#233). Follow-up to agent1 review of #229.

Tests

Same directed tests as #229; one-line close handler. No Playwright locally.

Note

Low Risk
Single close-handler change that resets in-memory UI bind state; no auth, persistence, or API changes.

Overview
Fixes a state leak when users dismiss the layer asset explorer without completing a bind. Closing the explorer (Cancel/Escape) now clears pendingBindRef and reassignId in addition to hiding the dialog, so a stale capture cannot be applied if a file picker or other flow runs afterward.

This aligns explorer dismissal with successful commit paths that already null the pending bind after applyLayerSourceCommit.

Risk: low
Scope: 1 file(s); +1/-1; React UI

Automated review from scripts/analyze_pr.py. This is a heuristic pass (no LLM) so humans still own the merge decision.

Findings

• low — UI changed — rebuild before merge
  Run cd ui && npm run build (CI already does this). Pinokio Update rebuilds for end users; keep ui/dist untracked.

Changed files

• modified: ui/src/components/Sidebar/SceneAnimatorPanel.tsx

CONTRIBUTING checklist

• python scripts/verify_clean_repo.py
• python -m compileall -q app/services app/launch.py scripts
• cd ui && npm run build if the UI changed
• No weights, CivitAI sidecars, or generated guides
• Stays local-first (no required accounts / telemetry)
