 * @param {AppSharedState} state - The shared application state containing rendering layers and other data.
 * @param {string | undefined} key - The key of the rendering layer to search for.
 * @returns {PantherEntityWithNeighbours | undefined} The metadata of the layer associated with the rendering layer key, or `undefined` if not found.
