yoda: iced_widget cleanup (7→0 warnings)

- overlay/menu.rs:578: real bug fix — List::draw was rendering with
  text::Wrapping::default() instead of the configured self.text_wrap.
  Wiring it through eliminates the 'field never read' warning AND
  honors the wrap setting that was being silently dropped.
- slider.rs:735-744: replace `if let Ok(x) = …try_into() { … }` with
  irrefutable `let Ok(x) = …try_into();` (the conversion is provably
  Infallible at the call site). Same behavior, no compiler noise.
- lazy.rs:8 / lazy/component.rs:13: drop unused
  `iced_renderer::core::widget::Operation` imports.
