feat: auto-create local workspace mirror for Gitea projects

- Opening /gitea-workspace auto-creates a local workspace with same name
- New Page/New Folder in remote context → saves to local mirror workspace
- Sidebar stays focused on remote workspace (🔗 icon, remote tree)
- local_ws_id passed to Alpine for API calls
- /api/local-workspace/items accepts workspace_id in body
