fix: workspace delete mixed-content error via top-level endpoint

- Add top-level DELETE /workspaces/{workspace_id} endpoint (avoids nested path)
- Frontend deleteWorkspace now uses /workspaces/{id}/?force=... (no project/repo needed)
- Update useWorkspaceActions, ProjectsPage, WorkspacesPage to match new signature

Quality gates: ruff clean, tsc --noEmit clean, pytest workspaces API (9 passed, 1 skipped)
