cli/fmt(fix[path-privacy]): collapse config paths in logs

why: fmt still leaked full config paths when reporting results, unlike other CLI commands.
what:
- cache a PrivatePath display string inside format_single_config
- use the redacted form for not-found, already formatted, issue summary, and success logs
- emit PrivatePath entries for fmt --all config listings
