input type="range" is inert (no rendering, no interaction)

`` renders nothing and has no pointer interaction — `events/mouse.rs` only implements click handling for checkboxes, and `oninput`/`onchange` never fire.

With `onmounted`/element-relative coordinates also unavailable through dioxus-native, an app cannot even build its own slider from primitives (there's no way to map a click to a track fraction). Sliders are load-bearing UI for media apps — seek bar, volume — which currently have no path to working at all.
