feat(auth-api): implement Tier 1 Traefik Ingress Control & Bypass Matrix

- Add idempotent migrations for `is_public`, `bypass_paths`, and `allowed_cidrs` in `server/db.ts`.
- Update `AppRecord` and `getAppByHost` in `server/auth-session.ts` to cache bypass rules in Valkey.
- Implement native Deno, fast-path prefix (`isPathBypassed`) and CIDR matchers (`isIpAllowed`).
- Update `GET /api/forward-auth` to evaluate dynamic rules and properly return 302/403 for unregistered domains.
- Create `ui/components/UnregisteredAppPage.tsx` SSR view for browser fallbacks.
- Update `AdminAppsPage.tsx` to handle the new ingress settings visually and post to `/api/admin/apps`.
- Add `POST /api/guests/sandbox` to generate ephemeral Valkey guest sessions.
- Update `POST /api/register/verify` to detect `upgrade_session` and promote guests to full users in-flight.
- Add `docs/TIER1_INGRESS_SPEC.md`.
- Ensure tests run cleanly and add comprehensive unit test cases for the bypass matrix.

+# Tier 1 Universal Global Edge Ingress Protection Specification
+
+**Specification ID:** RFC-SPEC-2026-INGRESS-01 **Classification:** Ingress
+Security & Traefik Routing **Status:** Canonical / Implemented
+
+---
+
+## 1. Executive Summary
+
+This specification outlines the Tier 1 Ingress Control strategy using Traefik's
+`ForwardAuth` middleware combined with a dynamic Valkey-backed authorization
+matrix within `auth-api`. The system provides highly performant (microsecond
+latency) dynamic bypasses, strict SSR unregistered fallbacks, and router-level
+self-exemptions.
+
+---
+
+## 2. Traefik Entrypoint Configuration
+
+To enforce zero-trust global edge protection, the `ForwardAuth` middleware is
+bound directly to the global HTTPS entrypoint. This ensures that _every_ service
+routed through Traefik is automatically intercepted without relying on
+developers to attach middleware to individual container labels.
+
+### Global ForwardAuth Middleware
+
+```yaml
+# infra/compose.yml snippet (Traefik labels)
+services:
+  traefik:
+    labels:
+      - "traefik.http.middlewares.auth-forward.forwardauth.address=http://auth-api:3000/api/forward-auth"
+      - "traefik.http.middlewares.auth-forward.forwardauth.trustForwardHeader=true"
+      - "traefik.http.middlewares.auth-forward.forwardauth.authResponseHeaders=X-Forwarded-User,X-Forwarded-User-Id,X-Forwarded-Scopes,X-Forwarded-App-Id"
+```
+
+---
+
+## 3. Router-Level Self-Exemptions
+
+Applying ForwardAuth globally creates an infinite redirect deadlock if
+`auth-api` intercepts requests destined for its own login mechanisms. To resolve
+this, explicit routes must be exempted at the Traefik router level by
+intentionally _not_ attaching the `auth-forward` middleware or configuring a
+bypass.
+
+### Required Exemptions
+
+1. **Authentication API / UI (`auth.atyg.org`)**
+   - The central Identity Provider must be explicitly bypassed.
+2. **ACME Challenge (`/.well-known/acme-challenge/*`)**
+   - Let's Encrypt automated HTTP-01 certificate renewals must proceed
+     unauthenticated.
+3. **Global Health Checks (`/healthz`)**
+   - Orchestration systems must be able to verify container readiness.
+
+---
+
+## 4. Auth-API Dynamic Bypass Rules
+
+Instead of volatile Traefik HTTP Dynamic Providers, Auth-Yes maintains a
+highly-performant cache in Valkey (L1/L2) under the key
+`auth:app_by_host:<host>`. When a request arrives at `/api/forward-auth`, the
+gateway evaluates the following dynamic properties before validating sessions:
+
+1. **`is_public` (Boolean)**
+   - If true, the entire application domain bypasses session checks.
+2. **`bypass_paths` (List of Strings)**
+   - Fast deterministic prefix matching (`/api/public/*`) and exact matching
+     (`/webhook`).
+3. **`allowed_cidrs` (List of Strings)**
+   - Fast native Deno IPv4 subnet matching to allowlist specific networks (e.g.,
+     internal CI/CD).
+
+If any of the above rules evaluate to true, `auth-api` immediately returns
+`200 OK` (with `X-Forwarded-App-Id` injected).
+
+---
+
+## 5. Unregistered Application Protocol
+
+If a domain is not registered in the central `apps` table (and therefore not in
+the Valkey cache), `auth-api` strictly denies the request.
+
+- **Browser Access (`Accept: text/html`):** The proxy returns an HTTP
+  `302 Redirect` to `https://auth.atyg.org/errors/unregistered?host=<domain>`.
+- **API Access (Non-HTML):** The proxy returns an HTTP `403 Forbidden`
+  (`{"error": "Application not registered"}`).
+
+This mechanism explicitly prevents open-redirect and infrastructure mapping
+attacks.
