feat(web): refresh the current view after deleting a song or playlist

Deletes left the removed item visible because the list loaders are cached (getPlaylists
~3 min): deletePlaylist navigated to a still-cached list, and deleteSong only reloaded
playlists. Add refreshCurrentView() — drops the API cache and re-runs the active nav
entry's loader (playlists, playlist/album/artist detail, starred, home, …). deleteSong
calls it after the delete+rescan delay; deletePlaylist invalidates getPlaylists before
navigating. Bump SW cache to ns-v46.

Also record the post-1.2 work in the 1.2 changelog (importer Enter, search single-song
+ radio, NowPlaying order, official-audio artist-metadata match, JP-katakana album
artist fix, year back-fill, delete refresh).

CHANGELOG.md

@@ -61,16 +61,23 @@ Follow-up to 1.1: web history navigation, correct download tagging for mixed-art
 
 ### Added
 - **Android** — Directional bottom-nav tab transitions: the slide follows the tapped tab's position (a tab to the right slides in from the right, one to the left from the left) instead of a fixed, sometimes-random-feeling direction. Applied across all four enter/exit/pop transitions; detail-screen push/pop is unchanged
+- **Web** — Pressing **Enter** in the importer link field starts the import (same as the Importieren button)
 
 ### Fixed
 - **Web** — Browser / mouse **Forward** navigation now works (previously only Back did): `popstate` applies the target history entry (`nsIdx`) for both directions, and the back handler no longer `pushState()`s over the browser's forward stack. In-app back buttons route through `history.back()` so the browser and app stacks stay in sync
+- **Web** — Deleting a song or playlist refreshes the current view immediately (drops the cached list) instead of leaving the removed item visible for up to ~3 minutes
 - **Web** — Album detail header showed the **first track's** artist (e.g. "TWICE" on a soundtrack) instead of the album artist; it now reads the album's own album-artist fields from `getAlbum` (matches the Android app)
 - **Web** — Metadata autofill (iTunes / MusicBrainz) normalizes the trailing `" & "` in a multi-artist credit ("A, B & C" → "A; B; C"), but only when the value is already a list, so band names like "Simon & Garfunkel" stay intact
 - **Android** — Erkunden (Apple) overlay back no longer *sometimes* jumped to Home: the root-level back callback is re-asserted on every navigation, so it can't lose back-priority to the NavHost after an album drill-down or tab switch
 - **Backend (download)** — Mixed-artist albums search **per track**: the YTM/YouTube query and channel filter use each track's own performer, so soundtrack tracks by other artists (TWICE's "Strategy", MeloMance's "Love, Maybe") are found instead of failing with "Nicht eindeutig gefunden"
 - **Backend (download)** — `album_artist` is derived from iTunes' album-level `collectionArtistName` (identical across the album) instead of the request's artist — which could be the lead single's performer, so a whole KPop soundtrack was tagged `album_artist = TWICE`. Applies to album and artist downloads; each track still gets its own per-track artist tag
+- **Backend (download)** — Official audio is matched by yt-dlp's `artist` metadata, not just the channel name, so uploads on label channels (BANGTANTV, HYBE, "… - Topic") win over fan reuploads — e.g. BTS "Pied Piper" now grabs the official track. (`channel_is_verified` was rejected as a signal: lyric videos and fan MVs are also on verified channels)
+- **Backend (download)** — Western artists are no longer tagged with the Japanese store's katakana album-artist ("DJスネイク" for DJ Snake): the JP-first iTunes lookup now keeps Japanese names only for Japanese songs and uses the US/English names otherwise (affects the `album_artist` tag and the on-disk folder)
+- **Backend (download)** — Release year is back-filled from iTunes on single-track downloads where the source omitted it (the year tag was previously left empty)
 
 ### Changed
+- **Web + Android** — Playing a song from search results queues only that song; Radio mode (if on) fills the rest — closer to Spotify. Album / playlist play still queues the whole list
+- **Android** — NowPlaying track info is ordered title → album → artists, matching the web player
 - **Web** — NowPlaying favorite star is vertically centered with the whole title / album / artist block instead of pinned to the title line
