[CLI] Add `hf spaces ssh` (#4241)
* [CLI] Add `hf spaces ssh <space_id>`
* [CLI] Improve `hf spaces ssh`: dev_mode check, --dry-run, --auto
- Fix dev mode detection: use `SpaceRuntime.dev_mode` (from API `devMode`
field) instead of checking `subdomain` presence.
- Rename `--print` to `--dry-run` (follows gcloud/git/make convention).
- Add `--auto` flag to enable Dev Mode without prompting.
- If dev mode is off, prompt user to enable it (interactive confirm).
- Extract `_wait_for_dev_mode` helper shared by `dev-mode` and `ssh`.
- Remove unnecessary `FileNotFoundError` catch on `ssh` subprocess.
- Mention `hf spaces ssh` in `dev-mode` output.
