RGB to hex

The RGB to hex node is a simple conversion utility that turns an RGB color object into a hexadecimal string (e.g., #FF5733).
When to use this node:
* Web Dashboards: Passing color data to a REST API or MQTT writer to update the background color of a custom web-based player interface.
* CSS Styling: Dynamically generating style properties for UI elements in the Room Master's control panel.
