Give the sliders a typed value without touching a single call site

float_row() and int_row() keep the signature they had. The edit icon is
drawn first, at the right end of the row, and the slider after it, so the
slider is still the last item submitted and the hover_tip() every caller
already writes after the row still describes the slider rather than the
icon. The range note moves onto the icon's own tooltip, which this helper
owns, instead of being threaded through every row as an extra argument.

That leaves the forty-odd rows in the panel byte for byte as they were,
which is what lets the branches that edit some of those rows - the model-UV
one above all - merge in any order. The two members and the edit icon also
move off lines a neighbouring branch inserts at.

 **Pitfall.**
-- **Rule:** On NVIDIA reach for `WEBKIT_DMABUF_RENDERER_FORCE_SHM` before
-  `WEBKIT_DISABLE_COMPOSITING_MODE`. **Why:** the proprietary driver cannot back WebKit's hardware
-  DMABUF renderer, leaving web views blank or slow; FORCE_SHM keeps accelerated compositing and only
-  skips the hardware path, while disabling compositing drops it. Threaded scrolling is a separate,
-  release-dependent default (off in 2.44/2.45, on from 2.46). `WEBKIT_DISABLE_DMABUF_RENDERER` is not a
-  substitute — it is read first, leaves the transport set empty (no compositing from 2.44 on, where the
-  X11/Wayland fallback renderers were removed) and has a reported crash path. On Debian/Ubuntu and
-  openSUSE the `isNVIDIA()` patch returns before the FORCE_SHM check, so `WEBKIT_FORCE_DMABUF_RENDERER=1`
-  must clear it first; that variable exists only in those patches. WebKit reads all of these once per
-  process, before the first WebView.
-  The test is `/proc/driver/nvidia/version`, so a hybrid laptop that renders on its iGPU also takes the
-  shared-memory path, which is a per-frame GPU readback rather than zero-copy; exporting
-  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=0` in the environment restores the hardware path.
-  ```cpp
-  // Wrong: kills compositing and threaded scrolling (and can crash on modern WebKit)
-  ::setenv("WEBKIT_DISABLE_DMABUF_RENDERER", "1", false);
-  // Right: keep compositing, skip only the hardware DMABUF path
-  if (::access("/proc/driver/nvidia/version", F_OK) == 0 && WebView::SupportsForceSharedMemory()) {
-      ::setenv("WEBKIT_DMABUF_RENDERER_FORCE_SHM", "1", /*replace*/ false);
-      ::setenv("WEBKIT_FORCE_DMABUF_RENDERER", "1", /*replace*/ false);

-  Cite: WebKit 2.52.6 `Source/WebKit/UIProcess/gtk/AcceleratedBackingStore.cpp`
-  (`rendererBufferTransportMode()`), Debian `disable-nvidia-dmabuf.patch`, WebKit bug 262607.
 - **Rule:** Set `WEBKIT_DISABLE_COMPOSITING_MODE` only on the default path in Wayland sessions,
   non-replacing (`setenv(..., false)`, so a value the user already exported wins), before GTK
-  initialises; never unconditionally, and only for the WebKitGTK releases that need it (older than
