1. portal.ts:138 — add null guard for portalSession before accessing .id
   (TS18048: 'portalSession' is possibly 'undefined')
2. rbac.ts:130 — guard jwt.email before split() to prevent runtime throw
3. portal.ts:39,105 — externalize DEMO_STAFF_ID as env var
   (process.env.DEMO_STAFF_ID ?? "00000000-...")
