feat(ui): implement App Launchpad and secure logout redirect

- Add isSafeRedirectUrl utility to prevent open-redirect vulnerabilities.
- Update GET /logout to handle ?redirect=, clear cookies safely, and log audit events.
- Create AppLaunchpadPage.tsx using pure Hono SSR JSX for application visibility and SSO launching.
- Update GET /dashboard and AuthenticatedLayout.tsx to mount the Launchpad as the default authenticated view with Zero-Knowledge querying.
- Add HYBRID_INGRESS_PLAYBOOK.md documentation for Traefik ForwardAuth routing.
- Implement exhaustive unit tests in server/main.test.ts for redirect preservation, anomaly logging, and Zero-Knowledge role filtering.

+# Hybrid Ingress Routing Playbook
+
+This playbook outlines the recommended architecture for deploying consumer
+applications that require a combination of public-facing endpoints (like splash
+pages or APIs) and private, authenticated endpoints (like control panels or user
+dashboards), while integrating with Auth-Yes.
+
+## Context
+
+Many applications are not entirely public or entirely private. They utilize a
+hybrid approach where certain paths are accessible to anyone, while others are
+strictly protected. To achieve Zero-Trust security and streamline
+authentication, we use a dual-routing pattern leveraging Traefik and
+application-level SSR hydration.
+
+## The Dual-Routing Pattern
+
+The dual-routing pattern separates responsibilities between the edge proxy
+(Traefik) and the application itself.
+
+### 1. Edge Proxy Authentication (Traefik ForwardAuth)
+
+For paths that must be strictly private and require a valid user session (or
+machine identity), we use Traefik's `ForwardAuth` middleware. This delegates the
+authentication decision to the Auth-Yes edge node.
+
+**Protected Paths:**
+
+- `/control-panel/*`
+- `/dashboard/*`
+- `/ws/*` (WebSockets)
+- `/api/private/*`
+
+**How it works:**
+
+1. A request arrives at Traefik for a protected path (e.g.,
+   `/control-panel/settings`).
+2. Traefik intercepts the request and sends a sub-request to the Auth-Yes
+   `ForwardAuth` endpoint (`/api/forward-auth`).
+3. Auth-Yes validates the `session_id` cookie or RFC 9421 HTTP Message
+   Signature.
+4. If valid, Auth-Yes returns HTTP 200 OK, injecting context headers like
+   `X-Forwarded-User` and `X-Forwarded-Scopes`.
+5. Traefik allows the original request to proceed to the application.
+6. If invalid, Auth-Yes intercepts with a redirect (for browsers) or 403
+   Forbidden (for APIs/daemons).
+
+**Example Traefik Configuration (Labels):**
+
+```yaml
+labels:
+  - "traefik.http.routers.myapp-private.rule=Host(`myapp.atyg.org`) && (PathPrefix(`/control-panel`) || PathPrefix(`/api/private`))"
+  - "traefik.http.routers.myapp-private.middlewares=auth-yes-forwardauth"
+  - "traefik.http.middlewares.auth-yes-forwardauth.forwardauth.address=http://auth-api:8000/api/forward-auth"
+  - "traefik.http.middlewares.auth-yes-forwardauth.forwardauth.trustForwardHeader=true"
+  - "traefik.http.middlewares.auth-yes-forwardauth.forwardauth.authResponseHeaders=X-Forwarded-User,X-Forwarded-Scopes"
+```
+
+### 2. Application-Level Authentication (SSR Hydration)
+
+For paths that are public or require custom application logic to handle
+unauthenticated users gracefully, the application itself handles the
+authentication state via SDKs or custom logic.
+
+**Public/Hybrid Paths:**
+
+- `/` (Splash page, landing page)
+- `/about`
+- `/api/public/*`
+- `/.well-known/*`
+
+**How it works:**
+
+1. A request arrives at Traefik for a public path (e.g., `/`).
+2. Traefik routes the request directly to the application (no `ForwardAuth`
+   middleware applied).
+3. The application receives the request. It can check for the presence of a
+   `session_id` cookie if it wants to render personalized content (e.g.,
+   replacing "Login" with "Go to Control Panel").
+4. If no session exists, it renders the public splash page.
+
+**Example Traefik Configuration (Labels):**
+
+```yaml
+labels:
+  - "traefik.http.routers.myapp-public.rule=Host(`myapp.atyg.org`)"
+  # No ForwardAuth middleware here
+```
+
+## Summary
+
+By combining Traefik `ForwardAuth` for strict edge-level protection of critical
+paths with application-level handling for public paths, we achieve a robust,
+flexible, and secure ingress architecture. This ensures that sensitive routes
+are never accidentally exposed, while public routes remain performant and
+accessible.
