LR-CROP-STRAIGHTEN: the Angle field reads decimal commas

egui's own parser dropped "-3,25" silently, while the Straighten value
takes it (issue #322). The field now reads a typed angle through the
same `typed_value`: a decimal comma, a trailing degree sign, and an
angle past ±45° held at the limit.
