/**
 * Recursively copies a folder and all its contents from a source path to a destination path.
 *
 * This function synchronously copies a directory from the specified source path to the destination path.
 * If the destination directory does not exist, it is created. The function then reads the contents of the
 * source directory, and for each entry, it checks if it's a directory or a file. If it's a directory,
 * the function is called recursively to copy its contents. If it's a file, the file is directly copied.
 * This process ensures that the entire directory tree structure from the source is replicated at the destination.
 *
 * @param src The source path of the folder to be copied.
 * @param dest The destination path where the folder should be copied.
 * @throws {Error} Throws an error if the source path does not exist or if there are issues in accessing the source or destination.
