modules: consistency pass over patches and option docs

- pinned-desktop (VERSION 3): drop the stop() of a predecessor global that
  never existed in this repo; log errors as "sfui <NAME>:" through one
  guard helper, like the grid patch.
- steamCloseButton.enable is a mkEnableOption like the other feature
  switches; enable descriptions no longer end in a stray newline.
- launcher-menu.nix header lists show-all and no longer claims the patches
  use no webpack module; hiddenApps mentions showAllApps.
- Patch comments: frame-controls ring timing matches the code (half of
  longPressMs, at most 1 s), window-curvature names frame-controls as what
  moves its control into the bar, steam-close-button no longer refers to an
  unpublished version.
