crmsh.log lack marker to distinguish user command from internal sub-commands

When executing a high-level composite crmsh command such as

`adm@161-1:~> sudo -E crm cluster health sbd --fix
`

crmsh automatically runs multiple hidden internal subcommands.

All INFO log lines for both the original user command and every auto-spawned internal subcommand are printed without any distinguishing marker.

```

Start by tracing how the user command and auto-spawned subcommands are logged in crmsh.ui_context, using the crmsh.log example as the behavioral reference. Review the related crmsh.utils and crmsh.sbd logging paths to understand whether the marker belongs at command dispatch or log formatting. Done means INFO entries distinguish the original command from internal subcommands without obscuring the command text.
