docs(UAT_PLAYBOOK): document canonical source-of-truth for UAT seed passwords (GRO-2000)

The 'Source of truth for UAT passwords' subsection under Pre-conditions
records:

- The seed-uat-passwords Secret in groombook-uat is the live source.
- The Bitnami SealedSecret apps/overlays/uat/ss-seed-uat-passwords.yaml
  in groombook/infra is the single upstream source of truth.
- A kubectl recipe to pull the current values for SUPER / GROOMER /
  TESTER / CUSTOMER at the start of every UAT run.
- The 'captured env var from a previous rotation produces 401' failure
  mode that GRO-2000 hit, and the manual-reseed escape hatch if the
  login still 401s after pulling the live value.

Refs: GRO-2000, GRO-1977 (idempotent re-hash), GRO-1999 (enum fix that
allowed the seed Job to run cleanly again).

+### Source of truth for UAT passwords (GRO-2000)
+
+The `UAT_SUPER_PASSWORD` / `UAT_GROOMER_PASSWORD` / `UAT_TESTER_PASSWORD` / `UAT_CUSTOMER_PASSWORD` env vars the test orchestrator uses **must** be pulled from the live `seed-uat-passwords` Secret in the UAT cluster — never from a captured shell value, a previous run's `.env`, or a copy of the SealedSecret committed before the latest rotation.
+
+**Canonical recipe** (works from any host with `kubectl` + cluster credentials):
+
+```bash
+SUPER=$(kubectl get secret seed-uat-passwords -n groombook-uat \
+  -o jsonpath='{.data.super-password}' | base64 -d)
+GROOMER=$(kubectl get secret seed-uat-passwords -n groombook-uat \
+  -o jsonpath='{.data.groomer-password}' | base64 -d)
+TESTER=$(kubectl get secret seed-uat-passwords -n groombook-uat \
+  -o jsonpath='{.data.tester-password}' | base64 -d)
+CUSTOMER=$(kubectl get secret seed-uat-passwords -n groombook-uat \
+  -o jsonpath='{.data.customer-password}' | base64 -d)
+```
+
+**Why:** the Bitnami SealedSecret `apps/overlays/uat/ss-seed-uat-passwords.yaml` (in `groombook/infra`) is the single source of truth. The UAT `reset-demo-data` CronJob re-hashes these values into the `account` table on every run (idempotent — GRO-1977). A captured env var from a previous generation will not match the current hash, producing 401 `INVALID_EMAIL_OR_PASSWORD`. If the live login still 401s after pulling from the SealedSecret, the seed Job is stale — trigger `kubectl create job --from=cronjob/reset-demo-data -n groombook-uat manual-seed-$$` and retry.
+
+**How to apply:** at the start of every UAT run that touches TC-API-1.4 / 1.5 / 1.6 / 1.7 / 3.18 / 3.21 / 3.23, refresh these four env vars from the cluster before issuing the sign-in request.
