Michal a2cda38850 feat: add node-runner base image for npm-based MCP servers ...

STDIO servers with packageName (e.g. @leval/mcp-grafana) need a Node.js
container that runs `npx -y <package>`. Previously, packageName was used
as a Docker image reference causing "invalid reference format" errors.

- Add Dockerfile.node-runner: minimal node:20-alpine with npx entrypoint
- Update instance.service.ts: detect npm-based servers and use node-runner
  image with npx command instead of treating packageName as image name
- Fix NanoCPUs: only set when explicitly provided (kernel CFS not available
  on all hosts)
- Add mcp-servers network with explicit name for container isolation
- Configure MCPD_NODE_RUNNER_IMAGE and MCPD_MCP_NETWORK env vars
