/**
 * Purges the entire cache.
 *
 * This event handler purges all entries from the configured cache.
 * It requires both `$rpcContext` and `$cache` to be present in the event context.
 * If either is missing, it returns a 500 Internal Server Error.
 * If the purge operation is successful, it returns a 200 OK with `{ success: true }`.
 * If an error occurs during purging, it returns a 500 Internal Server Error with `{ success: false }`
 * and logs the error using the logger provided by `$rpcContext`.
 *
 * @returns A promise that resolves to either an object indicating success or a `Response` object indicating an error.
