Template copy now carries choose_mode from the content project → studio store gets
chooseMode; AddSceneMenu returns null for FIX/MusicVisualizer. Admin ProjectScenes
hides '+ صحنهٔ جدید' (shows an 'scenes defined in AE' note) for fixed modes. Verified
choose_mode=FIX flows end-to-end. (Visible admin nav link added earlier.)

Build now (and every studio/image editor id generation) called crypto.randomUUID,
which is undefined outside a secure context — so over http://<LAN-IP> (used because
localhost is VPN-hijacked) the click threw 'crypto.randomUUID is not a function' and
the spinner hung forever, never reaching the editor.
Add lib/uuid.ts (crypto.randomUUID → crypto.getRandomValues → Math.random fallback)
and use it in studio-store, image-editor-store, project-defaults, dev-mock-project.
Verified headless (Chrome over http://172.28.144.1): Build now → 201 → navigates to
/studio/video/<id> → editor renders Scene 1 with editable title/subtitle fields.
