fix(cli): print progress messages to a dedicated non-recording console

progress_cb was wired directly to console.print, the same recording
console save_report() exports from. The "Probing <target>:<port> for PQC
key exchange…" progress line was appended to the record buffer, so
--output files started with that line before the actual report.

+### Fixed
+- `cli.py`: the `check` command's `progress_cb` now prints to a dedicated,
+  non-recording `Console` instead of the shared recording console from
+  `reporter.py`. Previously the "Probing <target>:<port> for PQC key
+  exchange…" progress line was appended to the record buffer that
+  `save_report()` exports from, so `--output` files started with that line
+  before the actual report.
