GRM-17: fix grm list status — use docker inspect for docker mode, add host/user context

- Docker mode runners now check container status via docker inspect
  instead of systemctl is-active, avoiding false unknown when systemd
  service is missing or stderr output is discarded
- Binary mode still uses systemctl is-active with stderr suppressed
- Both modes now show a translated context message before the check so
  users know which host/user each BECOME password prompt belongs to
- Better ansible output filtering: strip CHANGED/FAILED/UNREACHABLE
  header lines and separator noise
- Map Docker container states (running/exited/dead) to systemd vocabulary
- All new user-facing messages fully translated (en/bg/de/ru/zh)
- 125 tests, 100% coverage, pyright clean, ruff clean
