feat: AIUI chat mode integration with iframe, context broker, overnight loop

- Chat mode: AIUI loads in sandboxed iframe at /dashboard/chat with transparent bg
- Mode switcher: Easy + Pro tabs only, Chat is a launcher button
- Keyboard shortcuts: Cmd+1 (Easy), Cmd+2 (Pro), Cmd+3 (Chat), Cmd+M (cycle)
- Directional transitions: chat slides from/to left, dashboard from/to right
- Context broker: postMessage protocol for quarantined AIUI communication
- AI permissions store: user-controlled toggles for data access categories
- Settings UI: AI Data Access section with per-category toggles
- AIUI container manifest and nginx proxy config for /aiui/
- Deploy script builds AIUI with /aiui/ base path
- Overnight loop infrastructure (loop.sh, prepare.sh, plan.md, prompt.md)
- Security hooks for autonomous overnight runs
