…ate and sanitize proxy headers

This commit adds the `trustProxyHeaders` option to `AngularAppEngineOptions` and `AngularNodeAppEngineOptions` to configure, validate, and sanitize `X-Forwarded-*` headers.
- When `trustProxyHeaders` is `undefined` (default):
  - Allows `X-Forwarded-Host` and `X-Forwarded-Proto`.
  - Intercepts `X-Forwarded-Prefix` and triggers a dynamic CSR deoptimization to skip SSR if present.
  - Logs an informative message when receiving any other `X-Forwarded-*` headers.
- When `false`:
  - Ignores and strips all proxy headers from the request.
- When `true`:
  - Trusts all proxy headers.
- When a string array:
  - Allows only the proxy headers provided inside the array.
