Correctness Sweep I — MUI v4 imports & ts-nocheck removal

Goal

Remove known correctness hazards blocking development.

Targets

• Replace @material-ui/* imports with @mui/*
• Remove @ts-nocheck in editor and app; add minimal types
• Ensure app still builds/boots after changes

Acceptance

• No remaining v4 imports; no ts-nocheck in core paths
• Smoke tests green; manual run shows editor screen
• See docs/QUALITY_CHARTER.md.
