Add Privacy Sandbox and Preferences Manager to the dashboard

[Copilot]

The app launched to a static dashboard with no way for new users to understand or try the core privacy pipeline. This adds two native app features that give users a genuinely interactive experience with their real vault data.

What's new

lib/features/dashboard/widgets/privacy_sandbox_card.dart

• Clean native query input + "Query" button — no curl commands or terminal aesthetic
• 4 preset chips: coffee, work, commute, health
• Queries the user's real preferences through the actual AutoRedactEngine pipeline
• Results displayed inline with redacted tokens ([EMAIL REDACTED], [PHONE REDACTED], [AMOUNT GENERALIZED], etc.) highlighted in amber
• Stats badges showing privacy level and redaction count
• "My vault →" link navigates to the Preferences Manager

lib/features/preferences/preferences_screen.dart (new screen at /preferences)

• Full CRUD manager for vault preferences
• Preference tiles showing key (cyan monospace) and value side-by-side
• Tap to edit via bottom sheet, trash icon with confirmation dialog to delete, FAB to add new
• Empty state with onboarding copy

lib/features/preferences/widgets/add_edit_preference_sheet.dart

• Modal bottom sheet for adding and editing preferences
• Key and value fields with validation; key field is locked in edit mode

lib/providers/preferences_provider.dart

• Riverpod AsyncNotifier wiring PreferencesService add/update/delete to the UI

lib/core/router/app_router.dart

• /preferences route added

lib/features/dashboard/dashboard_screen.dart

• PrivacySandboxCard inserted between Connections and Monetization sections as a staggered AnimatedListItem

Key difference from the landing page demo

The landing page shows scripted, pre-canned data in a terminal emulator. The Privacy Sandbox operates on the user's own preferences — data they can manage directly in the Preferences Manager — and passes it through the live redaction pipeline with no simulated steps.

Original prompt

Please create a UI for users that try out the tool. Currently it launches a black screen. Maybe use the same concept as the demo from landing page just actually wire it? Any ideas?

Copilot so it has the same exact functionality of the demo on the landing page? That's not really what I wanted.

You're right — replaced in 52046f0. The terminal/curl approach is gone and is now two genuinely native features:

Privacy Sandbox card (on the dashboard): a clean query input + preset chips that run your real preferences through the actual AutoRedactEngine. No curl commands, no scripted steps — type anything, hit Query, and see exactly what an AI agent receives with every redacted token ([EMAIL REDACTED], [PHONE REDACTED], etc.) highlighted in amber inline.

My Vault screen (/preferences, linked from the sandbox card): full CRUD manager for your vault preferences. Each entry shows as a tile (key → value). Tap to edit, trash icon to delete with a confirmation dialog, FAB to add new. The preferences you manage here are the exact data the sandbox queries — so changes immediately affect what the sandbox returns.

The landing page demo shows static pre-canned data in a terminal. This operates on your actual vault data with no terminal aesthetic at all.
