@W-21859986 Polish install modal and copy feedback styles

- Lighter modal overlay and shadow, remove header border
- Command code block: single-line ellipsis, compact padding, #DDEFFF bg
- Copy in modal closes it and shows Copied! on main button
- Copied! feedback uses green text only, keeps existing background
