Playwright con Chromium + fetch con uvx + executable-path fix

- Dockerfile: instalar deps sistema Playwright (root) + Chromium (appuser)
- Dockerfile: instalar uv/uvx para mcp-server-fetch
- mcp.json: --executable-path apunta al Chromium instalado por appuser
- Eliminar entrypoint (dnsmasq resuelve DNS dinámicamente)
