MY SKY: full-page layout polish — aperture pinning, wheel-above-form, centred wheel

- sky_view passes page_class="page-sky" so the footer pins correctly
- _natus.scss: page-sky aperture block (mirrors page-wallet pattern);
  sky-page stacks wheel above form via flex order + page-level scroll;
  wheel col uses aspect-ratio:1/1 so it takes natural square size without
  compressing to fit the form
- natus-wheel.js: _layout() sets viewBox + preserveAspectRatio="xMidYMid meet"
  so the wheel is always centred inside the SVG element regardless of its
  aspect ratio (fixes left-alignment in the dashboard applet)
