Subject: [PATCH] fix(ui): make Controls panel vertically scrollable

The control panel grew past one screen after the disk/jet additions
(Color model, Temperature, Jets section). egui::Window without a height
constraint just clips overflowing content. Give it a default width/height,
enable resizing, and wrap the body in ScrollArea::vertical so all sections
remain reachable.
