fix(GRO-2299): redact googleMapsApiKey from PATCH /api/admin/settings response

The PATCH handler returned the full businessSettings row via .returning(),
echoing the encrypted googleMapsApiKey ciphertext back to the caller. Wrap the
return in the existing redactSettings() helper (after a !updated guard) so
redaction is applied symmetrically with the GET projection (GRO-2294).

- src/routes/settings.ts: guard + redactSettings(updated) on PATCH return
- src/__tests__/settings.test.ts: assert PATCH omits googleMapsApiKey
  (existing-row and auto-create-then-update branches)
- UAT_PLAYBOOK.md §13 TC-API-13.2: assert PATCH response omits the secret
