Fix all broken shared libs, HTML script order, and duplicate code

- Fix vlm-toggle.js: missing return in getClient(), stray braces
- Fix api-key-manager.js: missing 'this.options =' in constructor
- Fix all index.html: move openai-client.js and vlm-toggle.js
  BEFORE app.js (restored from clean state, re-added correctly)
- Fix 16-ai-safety: remove duplicate DOM declarations, duplicate
  mode-toggle HTML, re-apply sample video feature cleanly

All 16 app.js files pass node -c syntax validation.
