Keep a long alert title on one line, ending in an ellipsis (0.2.64)

The title label had long_mode: DOT and a width but no height. LVGL 9.5 only
puts the dots on a label whose wrapped text is taller than the label, so the
label grew with its lines and a long title ran into the subtitle. It now has
one line of the headline font as its height (32 px Guition, 21 px CYD).

The Claude skill and the editor's alert tips said the CYD shows about forty
characters of a title; both screens show about twenty.
