feat: configure context7-mcp and proxmox-mcp as stdio servers

- Set context7-mcp restart: "no" for on-demand execution
- Add context7-mcp to crush.json mcp configuration
- Fix proxmox-mcp Dockerfile to use python module directly
- Update proxmox-mcp entrypoint to "python -m proxmox_mcp.server"
- Add git dependency for proxmox-mcp git+ dependencies
- Remove --frozen flag (no lock file available)
