fix(auth): add /api/readyz to auth middleware bypass list (GRO-2692)

/api/readyz is a public monitoring endpoint like /api/health.
app.basePath("/api") + api.use("*", authMiddleware) applies to all
/api/* paths regardless of route registration order (GRO-2692 UAT
failure: Hono basePath middleware bypass).

+### 4.19 Boot Resilience — ECONNRESET Recovery (GRO-2652)
+
+Verifies the API process does not crash on transient boot-time DB connection resets and that auth routes degrade gracefully until initialization succeeds.
+
+| TC | Test Case | Steps | Expected Result |
+|----|-----------|-------|-----------------|
+| TC-API-19.1 | Health endpoint available before auth init | 1. Deploy the image (or restart the api pod)<br>2. `GET /health` immediately (within first 2 s of pod start) | 200 `{"status":"ok"}` — server accepts requests before `initAuth()` completes |
+| TC-API-19.2 | Auth routes return 503 when auth not yet initialized | 1. Temporarily set `OIDC_ISSUER` to an unreachable host so `initAuth()` keeps retrying<br>2. `POST /api/auth/sign-in/email` during the retry window | 503 `{"error":"Authentication not configured"}` — process stays alive, does not exit |
+| TC-API-19.3 | Pod does not crash on first-attempt DB reset | 1. Review pod restart count after normal deployment<br>2. Confirm `kubectl get pod -n groombook` shows `RESTARTS: 0` (or same as before deploy) for the new pod | No new restarts — ECONNRESET causes retry, not process exit |
+| TC-API-19.4 | DB query retry log lines visible | After deploy, `kubectl logs -n groombook <api-pod>` | If any DB retry occurred, log lines matching `[auth] DB query attempt N failed` are present; on clean boot no retry lines appear |
+| TC-API-19.5 | Auth init retry log lines visible | When auth init fails and retries, check pod logs | Log lines matching `[auth] initAuth attempt N failed` present; process continues; no `process.exit` |
+| TC-API-19.6 | Auth succeeds after transient DB hiccup | 1. Allow pod to retry until DB is available<br>2. `POST /api/auth/sign-in/email` with valid credentials after init succeeds | 200 with session cookie — auth recovers without pod restart |
+| TC-API-19.7 | Normal sign-in still works end-to-end | Follow TC-WEB-SSO-3 (SSO sign-in) on UAT | Successful sign-in, staff list visible — no regression from resilience changes |
+| TC-API-19.8 | Public routes unaffected during auth retry | While auth is retrying (TC-API-19.2 setup), `GET /api/branding` | 200 with branding data — public routes bypass auth and serve normally |
+
+### 4.20 Portal OOBE — Create Client from Auth (GRO-2359)
+
+Verifies the `POST /api/portal/clients-from-auth` endpoint that creates a new `clients` row for a first-time SSO user (out-of-box-experience registration). This endpoint requires a valid Better Auth session but does NOT require a portal session; it is the pre-portal step in the new-user OOBE flow.
+
+| TC | Test Case | Steps | Expected Result |
+|----|-----------|-------|-----------------|
+| TC-API-20.1 | Successful client creation | 1. Sign in via SSO to obtain a Better Auth session<br>2. `POST /api/portal/clients-from-auth` with `{ "name": "Test User" }` | 201 `{ "id": "<uuid>", "name": "Test User", "email": "<sso-email>" }` — new `clients` row created |
+| TC-API-20.2 | All optional fields accepted | `POST /api/portal/clients-from-auth` with `{ "name": "Test User", "phone": "555-1234", "address": "1 Main St", "notes": "VIP" }` (authenticated) | 201 with `id`, `name`, `email`; row in DB has all four fields |
+| TC-API-20.3 | Invalid body — missing name | `POST /api/portal/clients-from-auth` with `{}` (authenticated) | 400 (Zod validation failure); no row created |
+| TC-API-20.4 | Invalid body — empty name | `POST /api/portal/clients-from-auth` with `{ "name": "" }` (authenticated) | 400 — name must be at least 1 character |
+| TC-API-20.5 | No session — 401 | `POST /api/portal/clients-from-auth` with a valid body but **no** Better Auth session cookie | 401 `{ "error": "Unauthorized" }` |
+| TC-API-20.6 | Existing email — 409 | 1. Create a client row whose email matches the signed-in SSO user's email<br>2. `POST /api/portal/clients-from-auth` as that user | 409 `{ "error": "A customer record with this email already exists" }` — no duplicate row |
+| TC-API-20.7 | Auth not configured — 503 | Temporarily disable auth (e.g., point `OIDC_ISSUER` to an invalid host) so `getAuth()` throws<br>2. `POST /api/portal/clients-from-auth` | 503 `{ "error": "Authentication not configured" }` — graceful degradation |
+| TC-API-20.8 | Concurrent insert race — 409 | Simulate two near-simultaneous requests from the same SSO user (before any row exists) | At most one request returns 201; the other returns 409 — no duplicate row, no 500 |
