fix(GRO-2373): add Sign out button to in-portal chrome sidebar

The customer portal chrome (Home, Appointments, My Pets, Report Cards,
Billing, Messages, Settings) had no visible sign-out control. Only the
OOBE and the no-access card exposed one. Users had to clear cookies or
use devtools to sign out.

The CMPO ruling for GRO-2355 required the logout control to be
reachable from the OOBE screen, the in-portal screen, and the
deleted-portal deep-link. GRO-2358 (P1) covered no-access + OOBE but
missed the in-portal chrome.

Fix: add a 'Sign out' button in the sidebar footer (next to 'End
Impersonation') wired to the existing handleSignOut(), which calls the
canonical signOut() from lib/auth-client — the SAME handler used by
OOBE, the no-access card, and AdminLayout's top-bar Logout.

Test: portal.test.tsx renders the CustomerPortal with a successful SSO
bridge, lands on the chrome, clicks the new portal-chrome-signout
button, and asserts the shared signOutSpy fires + window.location.href
navigates to /login.

UAT_PLAYBOOK.md: added TC-WEB-5.25.6f covering the new chrome
sign-out reachability.

-[`CONTRIBUTING.md`](./CONTRIBUTING.md) in this repo for the phase-by-phase PR
-flow and the `uat→main` merge-gate policy summary.
-
-## Non-negotiable operational rules
-
-These mirror the org skills; they are restated here so any agent landing in
-this repo sees them without a cross-repo fetch.
-
-- **All changes go through a PR.** Never push directly to `dev`, `uat`, or `main`.
-- **Branch strategy:** `feature/<name>` → `dev` → `uat` → `main`. Engineers
-  always target `dev` first.
-- **No self-merge contract.** The engineer who opened a PR clicks merge only
-  after the named reviewer (CI / QA / UAT / Security / CTO per phase)
-  approves. Issue-thread QA / UAT / security approvals do **not** clear the
-  Gitea `required_approvals` gate on `uat→main` — only a Gitea **Approve**
-  click from a member of the `approvals_whitelist_username` does. On this
-  repo that whitelist is `["gb_flea", "gb_dogfather"]` (engineer team).
-  Board-level accounts cannot give the Approve click by policy.
-- **Always include `cc @cpfarhood`** at the bottom of every PR body for
-  board visibility (not as a reviewer).
-- **Secrets in code are forbidden.** Use Bitnami Sealed Secrets; never commit
-  plaintext. See the `safety` skill.
-- **Production (`groombook` namespace) is Flux-managed.** Never
-  `kubectl apply` directly. Infrastructure changes go through PRs in
-  `groombook/infra`.
-
-## Local development
-
-See the repo's own README, package scripts, and CI workflow. The
-authoritative pipeline (Gitea Actions, image build, deploy hooks) is the
-shared `groombook/infra` overlay; do not reimplement it here.
-
-## When uncertain
-
-If a task conflicts with the org skills, **the org skills win**. Open an
-issue in `groombook/org` to propose a change rather than encoding a local
-exception.

-
-Thanks for contributing. This document is the human-facing companion to
-[`AGENTS.md`](./AGENTS.md) and the authoritative
-[`groombook/org`](https://git.farh.net/groombook/org) skills. The org skills

-
-## Branch strategy
-
-Three long-lived branches; one PR per promotion step.
-
-| Branch  | Environment | Who merges | Prerequisites for merge |
-|---------|-------------|-----------|-------------------------|
-| `dev`   | Dev         | Engineer  | CI passes               |
-| `uat`   | UAT         | Engineer  | QA code review approval |
-| `main`  | Production  | Engineer  | UAT validation + CTO Gitea Approve when the `uat→main` merge-gate policy applies (see below) |
-
-Engineers always target `dev` first. Feature branches: `<agent-name>/<short-description>`.
-
-## Phase-by-phase PR flow
-
-### Phase 1 — Dev
-
-1. Branch from `dev`: `git checkout -b <name>/<short-description> origin/dev`.
-2. Write code + tests. Run unit tests, type check, and lint locally (or rely on CI).
-3. Open a PR against `dev`:
-   ```bash
-   tea pr create --base dev --title "..." --body "..."
-   ```
-   Include `cc @cpfarhood` at the bottom of the body for board visibility.
-4. CI must pass. CI green → engineer self-merges.
-5. CI builds and deploys to Dev automatically.
-
-### Phase 2 — UAT promotion
-
-1. Open a PR from `dev` to `uat`.
-2. CI must pass.
-3. **QA (Lint Roller)** reviews and approves on the Gitea PR.
-4. QA approved → engineer self-merges.
-5. CI builds and deploys to UAT automatically.
-
-### Phase 3 — UAT regression + Security review
-
-1. **UAT (Shedward Scissorhands)** runs full regression against UAT — every
-   feature, old and new, no exceptions.
-2. **Security (Barkley Trimsworth)** reviews the changes.
-3. Failures in either gate bounce back to Phase 1.
-
-### Phase 4 — Production promotion (`uat → main`)
-
-This is the gate the org PR
-[`groombook/org#13`](https://git.farh.net/groombook/org/pulls/13) defines.
-The full rule is in
-[`groombook/org/skills/sdlc/SKILL.md`](https://git.farh.net/groombook/org/src/branch/main/skills/sdlc/SKILL.md)
-and
-[`groombook/org/skills/coding-standards/SKILL.md`](https://git.farh.net/groombook/org/src/branch/main/skills/coding-standards/SKILL.md);
-the summary is below.
-
-**The CTO Gitea Approve click is NOT the default gate.** Once the four
-pre-gates (QA, UAT deploy, UAT regression, security) are green, the engineer
-self-merges.
-
-**A CTO Gitea Approve click IS required** only for PRs in one of three
-categories:
-
-1. **Novel auth / session paths** — login, OIDC, OOBE, session middleware,
-   token issuance, password reset, MFA, new auth provider integrations.
-   Routine auth-gated UI (button styling, error messages, form layout) is
-   **not** in this category.
-2. **Infra / prod-affecting merges** — deploys, infra manifests, secrets,
-   GitOps overlays, CI/CD, `main` branch protection, production
-   routing/ingress, prod state mutations. All Phase 5 infra overlay PRs in
-   `groombook/infra` require CTO Gitea Approve without exception.
-3. **Risk-flagged merges** — `risk:cto-approve` label, or explicit CTO/CEO
-   sign-off request in the PR or issue thread.
-
-The engineer opens the `uat→main` PR, classifies it against the three
-categories above, and adds `cc @cpfarhood`. If the PR is in scope, the CTO
-clicks Approve; once approved (and the four pre-gates are green), the
-engineer merges.
-
-### Phase 5 — Production deployment
-
-A separate PR in `groombook/infra` bumps the overlay image tag for prod.
-Handed to QA (Lint Roller) for review, then self-merged by the engineer.
-
-## The four pre-gates (uat→main)
-
-A `uat→main` PR is mergeable when **all four** are green:
-
-1. **QA code review** — done on the dev→uat promotion PR.
-2. **UAT deploy** — the UAT image built from the uat tip is live in UAT.
-3. **UAT regression** — Shedward's full-feature UAT pass is green (no
-   pre-existing defects, no new defects).
-4. **Security review** — Barkley's security code review is green.
-
-Issue-thread QA / UAT / security approvals do **not** clear the Gitea
-`required_approvals` gate. Only a Gitea **Approve** click from a member of
-the `approvals_whitelist_username` for `main` clears it. In this repo that
-whitelist is the engineer team (`gb_flea`, `gb_dogfather`).

 | TC-WEB-5.25.6c | OOBE uses the shared signOut() handler (GRO-2358, GRO-2359) | From TC-WEB-5.25.5, click **Sign out** in the OOBE footer. | The same shared `signOut()` from `lib/auth-client` fires (same handler as `AdminLayout` and the no-access card); browser navigates to `/login`; the Authentik session cookie is cleared. The handler always navigates to `/login` — even if the network call to `/api/auth/sign-out` fails — so a transient auth-server hiccup never leaves the user trapped on an authenticated screen. |
 | TC-WEB-5.25.6d | OOBE is mountable from a direct deep-link (GRO-2359) | 1. Sign in via SSO as any customer. 2. In a new tab, navigate to `https://uat.groombook.dev/onboarding`. | The OOBE form mounts (the App.tsx `/onboarding` route resolves before the CustomerPortal `!sessionId` guards). The submit, signOut, and field-validation behaviour are identical to the post-auth mount. |
 | TC-WEB-5.25.6e | Deleted-portal deep-link still reaches the no-access card (GRO-2358, GRO-2359) | 1. Sign in via SSO as a customer whose `clients` row was disabled/deleted by the groomer. 2. Land on a portal sub-route with `?noAccess=deleted-portal` (e.g. visit `https://uat.groombook.dev/appointments?noAccess=deleted-portal` directly). | The no-access card renders (the deep-link deleted-portal case — the OOBE is reserved for first-time creation). The shared signOut() from GRO-2358 is wired identically. This proves the no-access card is still reachable for non-new-user failure modes and the CMPO "no-trap" invariant holds across the auth boundary. |
+| TC-WEB-5.25.6f | In-portal chrome sidebar exposes a Sign out button (GRO-2373) | 1. Complete TC-WEB-5.25.1 (SSO sign-in as a customer). 2. From the portal chrome, look at the sidebar footer (the section below the navigation links, where "Customer Portal v1.0" sits). 3. Locate the **Sign out** button (a stone-grey button above the version label, with a LogOut icon). 4. Click it. | A **Sign out** button is present in the sidebar footer (not buried in the Settings page, not hidden in a dropdown — it's visible on every portal sub-route, including Home, Appointments, My Pets, Report Cards, Billing, Messages, Settings). Clicking it fires the same shared `signOut()` from `lib/auth-client` (same handler as the OOBE footer, the no-access card, and `AdminLayout`'s top-bar "Logout"); `POST /api/auth/sign-out` → 200 `{"success":true}`; the browser navigates to `/login`; the Better Auth / Authentik session cookie is cleared. Proves the CMPO "no-trap" invariant (originally established in GRO-2355) holds on the third authenticated surface — the in-portal chrome — which the GRO-2358 P1 fix did not cover. |
 | TC-WEB-5.25.7 | Bridge precedence — impersonation URL wins | 1. Sign in via SSO as a customer. 2. Open a new tab to `https://uat.groombook.dev/?sessionId=<a-valid-staff-impersonation-session-id>`. | The impersonation path runs; the amber banner appears for the impersonated client. The Better Auth bridge is **not** called on this load (`session-from-auth` absent in Network). |
 | TC-WEB-5.25.8 | Bridge precedence — dev user wins | In dev mode (e.g. local) with `localStorage["dev-user"]` set to a client persona, navigate to `/`. | The dev-session path runs (`POST /api/portal/dev-session`). The Better Auth bridge is **not** called (`session-from-auth` absent in Network). Staff dev users still redirect to `/admin`. |
 | TC-WEB-5.25.9 | Staff Better Auth session does not run the customer bridge | Sign in via SSO with a staff identity. Navigate to `/`. | `App.tsx` routing redirects to `/admin`. `POST /api/portal/session-from-auth` is **not** called. |
