fix(security): relax Referrer-Policy and document HSTS_INCLUDE_SUBDOMAINS (#862) (#863)

- Change Helmet default from no-referrer to strict-origin-when-cross-origin
  so browsers send the origin on cross-origin requests, allowing Google Maps
  API key restrictions by HTTP referrer to work correctly
- Document HSTS_INCLUDE_SUBDOMAINS in all deployment artifacts:
  .env.example, docker-compose.yml, README.md, unraid-template.xml,
  charts/values.yaml, charts/configmap.yaml, wiki/Environment-Variables.md
