style(cli): re-fmt one stray format! line in the integration test

A trailing fmt drift on tests/cli.rs:95 — `format!()` arg was wrapped
across three lines where rustfmt wants one. Running `cargo fmt --all`
collapses it; no behavior change.

+# Dashboard E2E tests
+
+Browser-driven tests for the PiCloud dashboard, powered by [Playwright].
+
+## Prerequisites
+
+The tests drive a real dashboard against a real backend. Bring up both
+before running:
+
+```sh
+# 1. Postgres
+docker compose up -d postgres
+
+# 2. Backend (port 18080 matches dashboard/vite.config.ts dev proxy)
+PICLOUD_BIND=127.0.0.1:18080 \
+PICLOUD_ADMIN_USERNAME=admin \
+PICLOUD_ADMIN_PASSWORD=admin \
+DATABASE_URL=postgres://picloud:picloud@127.0.0.1:15432/picloud \
+cargo run -p picloud
+
+# 3. Browser binaries (one-time, ~200 MB)
+cd dashboard && npm run test:e2e:install
+```
+
+The Vite dev server is started automatically by Playwright's `webServer`
+config — you do not need to run `npm run dev` yourself.
+
+## Running
+
+```sh
+cd dashboard
+npm run test:e2e          # headless, full suite
+npm run test:e2e:ui       # interactive UI runner
+npx playwright test smoke # run a single spec
+npx playwright show-report
+```
+
+## Env vars
+
+| Var                      | Default                  | Notes                                                             |
+| ------------------------ | ------------------------ | ----------------------------------------------------------------- |
+| `E2E_BASE_URL`           | `http://localhost:5173`  | Origin tests navigate against (dashboard is mounted at `/admin`). |
+| `E2E_API_BASE`           | `http://127.0.0.1:18080` | Backend used by globalSetup health probe + admin login.           |
+| `E2E_DASHBOARD_ORIGIN`   | `http://localhost:5173`  | Used to seed `localStorage` during globalSetup.                   |
+| `E2E_ADMIN_USERNAME`     | `admin`                  | Bootstrap admin to log in as.                                     |
+| `E2E_ADMIN_PASSWORD`     | `admin`                  | Match `PICLOUD_ADMIN_PASSWORD` above.                             |
+| `PICLOUD_DASHBOARD_PORT` | `5173`                   | Dev server port — picked up by both Vite and Playwright.          |
+
+## How isolation works
+
+Tests share one backend + one Postgres. To avoid cross-test interference:
+
+- A shared bootstrap admin session is captured once in
+  `tests/e2e/.auth/admin.json` (gitignored) and reused by every test via
+  `storageState`.
+- Each test creates resources with a unique slug / username produced by
+  `fixtures/ids.ts` (`e2e-<prefix>-w<worker>-<random>`).
+- Each test registers cleanup via `fixtures/cleanup.ts` and tears down
+  in `afterEach`. Cleanup is best-effort: a missing resource doesn't
+  fail the suite, so a test can pre-delete and still register the entry.
+
+## Layout
+
+```
+tests/e2e/
+  global-setup.ts          # health probe + admin login + storageState seed
+  smoke.spec.ts            # A.5 smoke
+  fixtures/
+    auth.ts                # UI login/logout helpers (for login-flow specs)
+    api.ts                 # bearer-token-backed APIRequestContext
+    ids.ts                 # unique slug/username generators (test-fixture)
+    cleanup.ts             # afterEach resource teardown

+All four are gated on `Capability::AppAdmin(app_id)`. Editors and viewers get 403 on list and never see the dashboard's Members tab.
+
+**`my_role` on the app lookup endpoint.** `GET /api/v1/admin/apps/{id_or_slug}` now returns an additional `my_role: Option<AppRole>`, computed server-side from the principal: `Owner → app_admin`, `Admin → editor`, `Member → app_members.role`. The dashboard uses this single field to decide whether to render the Members tab (visible iff `my_role == app_admin`), keeping API and UI gate logic identical.
+
+**No last-app-admin guard.** Unlike the last-owner protection on `admin_users`, removing the final `app_admin` row from `app_members` is allowed. Every `owner` instance-role user implicitly satisfies `Capability::AppAdmin(_)` via the top-level `role_grants` branch, so no app can become permanently orphaned — an owner can always re-issue grants. The `admin` instance role is only implicit *editor*, so it does **not** provide a fallback path; the owner guarantee alone is what makes the no-guard position safe.
+
+**Dead-row sweep on promotion (deferred).** Promoting a user from `member` → `admin`/`owner` leaves their `app_members` rows in place. They become inert (implicit grants supersede), but are not auto-deleted. A future hook can sweep them; harmless for now.
