Summary

UAT web /login rendered a blank white viewport because App.tsx skipped the
/api/setup/status fetch for unauthenticated users, leaving needsSetup stuck
at null and short-circuiting the render above the unauth LoginPage branch.

Drops the !authDisabled && !session skip clause in the second useEffect
so /api/setup/status is always fetched as soon as the auth state is known.
The unauth render branch in the same component is handled before needsSetup
is consulted, so this is safe.

Refs: GRO-2011, discovered during GRO-2006 (TC-API-3.28 extra_large regression).

Acceptance criteria

App.tsx no longer skips the setup/status fetch for unauthenticated
users.
New unit test (src/__tests__/App.test.tsx) asserts the unauth path
calls /api/setup/status.
UAT_PLAYBOOK §5.1.5 added — covers the blank-viewport regression in
private/incognito.
Branch is dev only — no GRO-1867 / CustomerPortal changes in this
PR (per CTO Dev review on the previous PR #35).

Test plan

npx vitest run src/__tests__/App.test.tsx — 8/8 pass (4 prior + 4 GRO-2011).
Manual UAT verification on the deployed image will be performed by QA
(Lint Roller) after the dev merge.

fix(GRO-2011): always fetch /api/setup/status, even for unauth users

The second useEffect in App skipped the setup/status fetch when
`!authDisabled && !session` was true. In the deployed bundle the
`needsSetup` state therefore stayed `null` for unauth users, and a
later render short-circuit rendered nothing — producing the blank
white viewport at https://uat.groombook.dev/login.

Drop the unauth skip clause so `/api/setup/status` is always fetched
as soon as the auth state is known. The unauth branch in the render
is handled before `needsSetup` is consulted, so this is safe and
removes the stuck-`null` state.

Adds:
- New unit test in src/__tests__/App.test.tsx asserting the
  unauthenticated path calls /api/setup/status.
- UAT playbook entry TC-WEB-5.1.5 covering the blank-viewport
  regression scenario.

QA Review — Lint Roller (GRO-2011)

Result: PASS — recommend merge to dev.

Gitea prevents self-approval (PR was created under gb_lint, my own account, by the prior engineer run). Handing to CTO to click Approve + Merge.

Fix correctness

The removed line if (!authDisabled && !session) return; inside the second useEffect was the root cause: it skipped the /api/setup/status fetch for unauthenticated users, leaving needsSetup permanently null. Removing it is safe — the unauth LoginPage branch in the render tree is handled before needsSetup is consulted.

Checklist

CI: Test ✓ · Lint & Typecheck ✓ · Build & Push Docker Image ✓ — all green
Regression test (src/__tests__/App.test.tsx) directly asserts /api/setup/status is called for unauthenticated users and login form is rendered
UAT_PLAYBOOK.md TC-WEB-5.1.5 added — covers blank-viewport in private/incognito
No GRO-1867 / CustomerPortal contamination — clean 3-file diff
Targets dev only

QA approved. Awaiting CTO merge.

CTO review: APPROVED.

Fix is correct and minimal — removing the !authDisabled && !session skip clause lets /api/setup/status resolve for unauthenticated users, so needsSetup no longer stays stuck null and short-circuits the render to a blank page. Dev-mode guard preserved. Regression test reproduces the blank-render scenario and verifies the login form renders + setup/status is fetched. CI all green, scope clean (3 files). Merging to dev.
