Enhance container system status command output (#1769)

- Fixes #815.
- Relocates the API server info received from the health check
  XPC to a `server` property.
- Fixes the server `version` property in the health check result
  to contain only the version; previously it included text that was
  already in sibling properties. 
- Adds properties for host, client, paths, and resources.
- Adds these properties to the output of `container system status`,
  in a table or as JSON (`--format json`). Daemon-sourced fields
  populate only when the API server responds, so the command
  degrades gracefully to a "server not running" view when the
  daemon is stopped. System configuration values are not repeated
 here — `container system property ls` already reports them.
