sky.html: DEL btn at wheel center; async SAVE SKY transitions into saved state without reload; pre-save hides wheel-col so form+SAVE SKY stay centered — TDD

DEL btn (.btn-danger, "Forget sky?" data-confirm wired to the global #id_guard_portal) sits absolutely centered inside .sky-wheel-col; OK submits a POST to the new sky_delete view, which clears every sky_* field on the User model & redirects back to /dashboard/sky/.

The sky.html aperture is now uniform across saved/unsaved: form-col is always flex-column align-center justify-center so the fields + SAVE SKY pair sits visually centered. body.sky-saved adds *only* the snap-binary scroll layer (scroll-snap-type:y, modal-body display:contents, cols min-height:100% scroll-snap-align:start, wheel-col aspect-ratio cap released, form-col flex:0 0 auto so the snap basis wins) — the column-stacking is no longer gated.

Async save: SAVE SKY's success branch now calls _activateSavedState(), which adds body.sky-saved, draws the wheel from _lastChartData, pins overlay.scrollTop to the form section's offsetTop, then runs the existing _scrollApertureToTop ease-out so the wheel reveals from above instead of replacing the form with a hard cut. The wheel preview that previously redrew during typing is now gated on _savedSky — pre-first-save typing fetches the chart data (so SAVE SKY enables) but does not render the wheel, mirroring the My Sky applet's "no wheel until saved" UX. The in-room PICK SKY overlay (_sky_overlay.html) still previews live, deliberately untouched.

Pre-save the wheel-col is hidden via `body:not(.sky-saved) .sky-page .sky-wheel-col { display: none }`, so the empty SVG can't shunt the form below the fold (& the DEL btn rides the same selector since it lives inside .sky-wheel-col).

Tests: SkyDeleteTest IT class (5: clears fields, redirects, 405 on GET, login required, preserves unrelated user fields). MySkyDeleteFlowTest FT class (3: DEL btn visibility gated on sky data, NVM dismisses w. data intact, OK clears + reverts body class). MySkyAsyncSaveTest FT (1: fresh user → SAVE SKY → body picks up sky-saved, wheel SVG populates, DEL btn becomes visible — all without a page reload). All 13 sky FTs + sky ITs green; existing MySkyApertureSnapScrollTest & MySkyTimezoneRefreshTest still pass.
