demo-service: add login link to error page, mount ConfigMap into API container

Browse Source 
- Add subtle 'Log in' link to 401/403/404 error page
- Link redirects through pass.junv.cc OAuth with return URL
- Mount error-page-html ConfigMap into API container too (so both
  Caddy and API serve the same updated error page)
- Define error-page-html ConfigMap in repo for ArgoCD management
