/// Renders a title line with buttons aligned to the right.
///
/// This function creates a line where the title appears first, followed by
/// buttons rendered in reverse order so the first button in the list appears
/// rightmost in the UI.
///
/// # Arguments
///
/// * `panel_area` - The rectangular area available for rendering
/// * `title` - The title text to display
/// * `buttons` - Mutable slice of buttons to render (order determines visual position)
///
/// # Returns
///
/// A `Line` containing the title and button spans
///
/// # Example
///
/// ```rust
/// use ratatui::layout::Rect;
/// use ratatui_toolkit::{Button, render_title_with_buttons};
///
/// let panel_area = Rect::new(0, 0, 80, 1);
/// let mut btn1 = Button::new("Save");
/// let mut btn2 = Button::new("Cancel");
/// let mut buttons: Vec<&mut Button> = vec![&mut btn1, &mut btn2];
/// let line = render_title_with_buttons(panel_area, "My Panel", &mut buttons);
/// ```
