feat: add DB persistence, real-time WebSocket, goal preprocessor, and Android companion app

- Add device/session/step DB persistence in server agent loop
- Add goal preprocessor for compound goals (e.g., "open YouTube and search X")
- Add step-level logging to agent loop
- Fix dashboard WebSocket auth (direct DB token lookup instead of auth.api)
- Fix web layout to use locals.session.token instead of cookie
- Add dashboard-ws.svelte.ts WebSocket store with auto-reconnect
- Rewrite devices page with direct DB queries and real-time updates
- Add device detail page with live step display and session history
- Add Android companion app resources, themes, and screen capture consent
