v0.4.1 — Dioxus scroll-listener leak fix

Fixed

• Dioxus auto-scroll velocity decay across many drags. The window scroll event listener and the RAF generation counter were installed inside provide_dnd_context without a hook guard, so Dioxus's re-execution of the host component on every signal change attached a fresh forget()-ed listener per render. After ~20 drops the page was running 20+ scroll listeners per event, each calling remeasure_all + update_over, producing a linear slowdown of the auto-scroll loop (mouse-wheel scrolling, which fires few events, stayed fast). Wrapping the listener install in use_hook makes it run exactly once per component instance.

• Dioxus drop-preview flicker near viewport edges. bounding_rect now subtracts the element's computed transform: translate(...) before returning. Without this, mid-drag getBoundingClientRect captures the drop-preview transform and feeds it back into the registry, producing a flicker loop. Required enabling the CssStyleDeclaration feature on web-sys.
