* feat(api): serve portal-shaped health and error envelope
Move liveness to GET /api/health { stage, sha } with a Node 24 image on 8080 so ALB probes and deploy verify do not need auth or a database ping.

Replace Bearer as the documented session path with Cognito hosted UI plus __Host-ap_* cookies so the SPA can call /api with credentials include.

Land a credentials-include fetch helper and hand-synced health/me types without wiring pages or domain hooks, so mocks stay the default data path.

* feat(api): add invoice, line, and document stubs
* feat(api): add approval policy, inbox, and activity stubs
* test(web): fix SPA client fetch mock types
