fix: HTTP health probes use container IP for internal network communication
mcpd and MCP containers share the mcp-servers Docker network. HTTP probes must use the container's internal IP + containerPort instead of localhost + host-mapped port. Also extracts container IP from Docker inspect. Updated home-assistant template to use ghcr.io/homeassistant-ai/ha-mcp Docker image (SSE transport) instead of broken npm package.
