fix: add dashboard to CLI help epilogue and Docker CI smoke test

- Add hermes dashboard examples to the CLI help epilogue so users can
  discover the web UI command from 'hermes --help' output
- Add an independent 'Test dashboard subcommand' CI step that verifies
  'hermes dashboard --help' works in the Docker image, with its own
  mkdir/chown setup to remain independent of the prior smoke test step
- Prevents regressions like #9153 where the dashboard subcommand was
  present in source but missing from the published Docker image

Closes #9153
