feat: library browse navigation — restore filters, scroll, and search on back (#936)

* feat(albums): restore scroll position when returning from album detail

Save in-page scroll and grid depth when opening an album from All Albums,
then on browser back restore filters, preload enough rows, and apply scroll
before revealing the grid to avoid a visible jump from the top.

* feat(albums): smart back navigation and restore browse session on return

Remember the originating route when opening album detail, restore All Albums
filters/scroll on back (including explicit returnTo navigation), hide the grid
until scroll is applied, and fix filters being cleared after albumBrowseRestore
state is stripped from the location.

* feat(search): restore Advanced Search session when returning from album

Stash filters and results when leaving /search/advanced for album detail,
then restore them on back navigation (POP or returnTo with advancedSearchRestore).

* feat(search): restore Advanced Search album row scroll on return from album

Save horizontal scrollLeft when opening an album from Advanced Search and
reapply it via AlbumRow on return; keep main viewport at top. Add snapshot
helpers and session stash fields; extend AlbumRow with restoreScrollLeft.

* feat(search): restore Advanced Search session scroll and artist return path

Save filters, main scroll, and album-row scroll when leaving to album or
artist; restore without flash via hidden-until-ready. Add useNavigateToArtist,
restoreMainViewportScroll helper, and AppShell scroll reset only on pathname change.

* feat(search): speed up Advanced Search back restore and year-only queries

Reveal the page right after sync scroll instead of blocking on full viewport
and album-row restore. Retry local index without the ready gate during sync;
use open-ended byYear params on network fallback, matching All Albums browse.

* feat(search): restore Advanced Search artist row scroll on back

Save leave snapshot when opening artist from ArtistCardLocal, persist
artistRowScrollLeft in session stash, and keep row restore targets in refs
so horizontal scroll survives finishLeaveRestoreUi like vertical scrollTop.

* feat(nav): route mouse back on album/artist detail like UI back

Trap history popstate when returnTo is set and call navigateAlbumDetailBack
so browser/mouse back restores browse/search session the same way as the header button.

* feat(artists): restore browse filters and scroll on back from artist detail

Persist Artists page filters, view settings, and vertical scroll when opening
an artist and returning via UI or mouse back, matching All Albums behavior.

* feat(search): unify quick and advanced search; fix LiveSearch dismiss on Enter

Serve /search and /search/advanced from one page with shared session restore
and scroll snapshot. Reset live search overlay state when navigating to full
search so the dropdown does not linger or reopen.

* feat(tracks): unify with search session and restore scroll on back

Route /tracks through AdvancedSearch with shared leave snapshot, song
browse stash, and main-viewport scroll restore when returning from album
or artist detail. Wait for hero/rails layout before applying scroll.

* refactor(search): rename AdvancedSearch page to SearchBrowsePage

The shared route shell serves /search, /search/advanced, and /tracks;
rename the page component and refresh stale file references in comments.

* feat(albums): restore New Releases and Random Albums on back from detail

Unify album grid leave-restore with surface-scoped session stash, live scroll
snapshot sync, and in-page scroll for Random Albums. Keep the same random
batch when returning from album detail; Refresh fetches anew and scrolls up.

* docs: add CHANGELOG and credits for PR #936

+### Library browse — restore scroll, filters, and search when returning from detail
+
+**By [@cucadmuh](https://github.com/cucadmuh), PR [#936](https://github.com/Psychotoxical/psysonic/pull/936)**
+
+* **Artists, Search, Tracks, New Releases, Random Albums:** going back from album or artist detail keeps browse filters, list scroll, and search text instead of resetting the page.
+* **Search / Advanced / Tracks** share one browse page; the separate quick-search results route is removed.
+* In-app **Back** and the browser **mouse back** button on album/artist detail use the same return path to the browse session you left.
