fix(topola-egui): Always clamp `dt` to `i.predicted_dt` 

`egui` clamps its `i.stable_dt` to `i.predicted_dt` only when egui
requested a repaint during the last frame. I however sometimes
experience severe stuttering, which means that this detection
method is insufficient to ensure smoothness. So, let's clamp `dt` to
`i.predicted_dt` and see if this helps.
