paperclip: auto-attach default workspace on project creation

Without a primary workspace on a project, the "סביבות עבודה" tab in
Paperclip stays hidden (gate: enableIsolatedWorkspaces && S0t list
non-empty), and agents wake with cwd=`/home/chaim` instead of the
legal-ai source tree. New helper inserts a primary workspace pointing at
LEGAL_AI_WORKSPACE_CWD (default /home/chaim/legal-ai) on both new and
legacy/existing-project paths. Idempotent — skips if any workspace row
already exists.
