docs: fix config key names, add missing CDC key, update install version

- Fix cert_auth key names: user_cert_file/user_key_file →
  ace_user_cert_file/ace_user_key_file to match YAML struct tags
- Add missing mtree.cdc.cdc_metadata_flush_seconds to config table
- Update hardcoded v1.5.3 → v1.9.0 with a note to keep it current
