Subject: [PATCH] fix(sandbox): prevent server SIGHUP on sbx exec exit (#792)

Replace bare background operator with nohup+disown so the cloudcli
server process survives after the sbx exec session terminates.
Also redirects stdout/stderr to /tmp/cloudcli-ui.log for debugging
via `cloudcli sandbox logs`.

Fixes #791
