feat(ai): 🤖 Add MCP servers for shadcn, docker, n8n, coolify, and appwrite

Add new Model Context Protocol server configurations:
- **shadcn**: shadcn/ui MCP server using npx
- **docker**: Docker MCP server with custom Python path
- **n8n**: n8n workflow automation server with API configuration
- **coolify**: Coolify deployment platform MCP server
- **appwrite**: Appwrite backend server with full resource access

Each server includes appropriate environment variables for API keys and
endpoint configuration, following existing MCP server patterns in the
configuration file.
