/// Displays a paginated list of items with user interaction.

///
/// # Arguments

/// * `prompt` - A prompt message displayed to the user.
/// * `error_message` - An error message to display if there's an issue during interaction.
///
/// # Examples
///
/// ```
/// use your_crate_name::pagination_list;
///
/// let items = vec![
///     "Item 1".to_string(),
///     "Item 2".to_string(),
///     // Add more items...
/// ];
///
/// pagination_list(items, "Choose an item:".to_string(), "Error occurred during selection.");
/// ```
///
/// # Panics
///
/// Panics if parsing the number of items per page fails, printing a formatted error message.
