chore(curator): point backend at its new home under pi-workspaces

The curator application code has moved from
codex-workspace/server-management/deploy/curator to /home/claw/pi-workspaces/curator
(starting its own git repo with the preserved history). Update profile.toml's
backend and the plan's working-directory references to match.
