Update codex remote-control to start the daemon (#22218)

## Why
Update `codex remote-control` to use the new app server daemon commands
instead.
- if the updater loop is not running, bootstrap the daemon with remote
control enabled (`codex app-server daemon bootstrap --remote-control`)
- otherwise, enable the persisted remote-control setting and start the
daemon normally
