lisa.target: Fix Target.from(_custom)_cli annotations
Remove wrong return annotation on Target.from_custom_cli. Restore the explicit parameter list on Target.from_cli so that it can be picked up by exekall (--allow/--restrict is needed).
GitLab Maintenance scheduled for Thursday, 18th December 2025, from 7:00 AM to 10:00 AM BST. GitLab will be in read-only mode and experience short periods of complete downtime (up to 20 minutes) during this window.
