Update-Knopf: Seitensprung im Großbild-Layout behoben

Auf Update prüfen/Update installieren ließ die Seite im Seitenleisten-Layout
sichtbar nach oben springen - render()s eigene Scroll-Wiederherstellung
reichte hier nicht, vermutlich weil die Zustandsänderung des
Update-Sensors zusätzlich über HAs eigenes set-hass-Durchreichen an das
eingebettete Panel einen zweiten Render-Pfad anstößt. Statt die genaue
Ursache weiter zu jagen: fester Scroll-Merkwert vor dem Klick, per
requestAnimationFrame nach jedem eigenen render()-Aufruf dieses Ablaufs
erneut erzwungen. Live bei 1280x800 verifiziert: kein Sprung mehr.

+**A third same-day fix (2026.8.24.12): the update-button scroll jump, specifically in wide/desktop
+mode.** The owner reported the page visibly jumps when pressing "Auf Update prüfen"/"Update
+installieren" on a large screen. Reproduced live at `1280×800`: clicking the button while scrolled deep
+into "Einstellungen" (`scrollTop` ~1773) landed at `scrollTop` ~1517 after the click resolved — a real,
+non-zero shift, not the element being replaced (`main#view` stayed `isConnected: true` throughout, so
+it wasn't a full re-mount either) and not simply `scrollTop` reset to 0 the way section L's
+narrow-mode work had assumed for this kind of bug. `render()`'s own scroll-preservation
+(`v.scrollTop = gleicheAnsicht ? merkeScroll : 0`) should apply here (same route, same id) and normally
+does — the update flow specifically still lost position, most likely because the service call also
+triggers a *separate*, second re-render path outside `render()`'s own bookkeeping (`sensor.audi_dashboard_app_version`
+changing state reaches the embedded panel through Home Assistant's own `set hass()` plumbing, not
+through this app's `route`/`letzteAnsicht` mechanism at all) — plausible but not conclusively traced
+before the owner asked to move on rather than keep chasing the exact mechanism. Fixed pragmatically
+instead of surgically: the `data-update` click handler for `pruefen`/`installieren` now captures
+`$("#view").scrollTop` once before acting, and re-asserts it via `requestAnimationFrame` after *each*
+of its own `render()` calls (both the immediate one and the one in `.finally()`) — this corrects the
+position regardless of what else might be moving it, without needing to identify or touch whatever the
+second path turns out to be. Verified live at `1280×800`: repeated the exact same scroll-deep-then-click
+sequence that reproduced the bug: **no visible jump**, page stayed on the same section
+before and after. (Separately noticed, not fixed, not in scope of what was asked: the check's *result*
+only shows up in the currently-open tab after a full page reload, even though it's correctly persisted
+server-side immediately — confirmed via `docker logs` showing the check completed and a subsequent
+fresh page load showing the right "Verfügbare Version" — likely because nothing in this flow re-reads
+`sensor.audi_dashboard_app_version`'s `daten` attribute into `INTEGRATION_UPDATE` and re-renders when
+that entity's state changes out from under the open tab. Pre-existing, not caused by this fix, not
+reported by the owner as a problem — worth a look if it ever is.)
+
+Manifest bumped to `2026.8.24.12` for this fix.
