fix: workspace creation with stale directories and missing bind mount
- workspace_manager.py: remove stale workspace directories before cloning
to prevent 'already exists' errors from previous failed attempts
- workspaces.py: add ValueError -> 400 handling, keep 409 for duplicates
- test_tool_instances_legacy.py: fix broken patches for new helpers
(get_container_name removed, _ensure_backend_network_in_compose added,
workspace_id/ssh_key_ids mock attributes added)
- docker-compose.traefik.yml: add /data/working-copies bind mount
