docs(changelog): 2.3 — Pull-Stack, APK-Download-Fix, Alben-Tab-Scrollfix

Fasst die Aenderungen seit 2.2 als Release zusammen: image-basiertes
docker-compose.yml (Bauen wandert nach .dev.yml), der auf GITEA_URL
umgeschriebene APK-Asset-Download und der Alben-Tab-Fix, dazu das
veroeffentlichte versionCode 3. Am Handy bestaetigt: Update-Dialog,
In-Place-Install und die Scrollpositionen funktionieren.

-### Changed
-- **APK-Release auf versionCode 3** — enthält den Alben-Tab-Fix unten und erstmals die
-  Artist-Seiten-/Overlay-Scrollerinnerung (die steckte bis dahin in keinem gebauten APK).
+A deployment-and-delivery release: production **pulls pre-built images** instead of compiling on the
+server, the **APK download works again** (it had been broken by Gitea's own link host), and the
+scroll memory from 2.2 finally behaves on the Alben tab — plus it reaches an actual build.
+
+### Added
+- **Pull-based production stack** — `docker-compose.yml` now references
+  `${REGISTRY}/novasonic-frontend|-backend|-scrobble:${TAG:-latest}` and builds nothing on the host:
+  `docker compose pull && docker compose up -d`. Building locally from the Dockerfiles moved to
+  `docker-compose.dev.yml` (no registry needed there). Images are pushed from the dev machine with
+  `npm run push-images`. A `.dockerignore` keeps the frontend build context to what `vite build`
+  needs, so `android/`, `backend/` and `.git` no longer travel into the image.
 
 ### Fixed
-- **Alben-Tab sprang beim Zurück wieder nach oben** — ein `LaunchedEffect(albumSort)` scrollte auf
-  Position 0. Der feuert aber nicht nur beim Sortierwechsel, sondern auch bei jedem Neu-Composen,
-  also genau beim Zurückkommen aus einem Album: die gemerkte Position wurde sofort verworfen. Das
-  Hochscrollen sitzt jetzt in `LibraryViewModel.setAlbumSort()` und läuft nur bei echtem Wechsel.
+- **APK download failed with "Keine APK hinterlegt"** — Gitea builds `browser_download_url` from its
+  own `ROOT_URL`, which pointed at a host the backend cannot reach (a leftover from an earlier
+  network). The API call succeeded, so the download button appeared, but fetching the asset ran into
+  the dead address and fell back silently to a local file that does not exist. Asset and redirect
+  URLs are now rewritten onto `GITEA_URL`; if the Gitea path still fails, a warning log and the 404
+  body name both sources that were tried instead of claiming no APK exists.
+- **Alben tab jumped back to the top on Back (Android)** — `LaunchedEffect(state.albumSort)` scrolled
+  to item 0. That effect runs on first composition too, not only on a sort change, so returning from
+  an album discarded the position the ViewModel had correctly kept. Scrolling to the top now happens
+  in `LibraryViewModel.setAlbumSort()`, on a real sort change only.
+
+### Changed
+- **APK release at versionCode 3** — carries the Alben-tab fix above and, for the first time in a
+  published build, the artist-page and "Alle anzeigen" overlay scroll/search memory (2.2 shipped the
+  code, but the release APK predated it). Signed with the established debug key, so it installs
+  in place over versionCode 2 and app data survives.
