feat(home): broaden Because-you-like seed pool + tidy orphan card at 1080p (#493)

* feat(home): mix recently-played + starred into Because-you-like anchor pool

Anchor pool was sourced only from getAlbumList(frequent), so the rotation
cursor walked the same eight top-played artists no matter how varied the
rest of the listening history was. Round-robin merge of mostPlayed,
recentlyPlayed and starred (dedup by artistId) means each mount can land
on a different listening *mode* — heavy rotation, current focus, or
explicit favorites — instead of stepping through the same top-played
sequence.

Pool size 8 -> 12 to let the cursor visit all three modes before
wrapping. Visibility guard widened so the rail still renders when the
server has no frequent-play data yet but starred or recent items exist.
Zero new API calls — all three lists are already in Home's initial
fetch.

* fix(home): drop orphan 3rd Because-card in 2-col range, keep all 3 stacked on mobile

auto-fit grid wraps to 2 cols between 696-1051px container width, which
left the third card alone on a second row at 1080p. Container query
hides the 3rd card only inside that 2-col band; on wider screens the
full 3-up row stays, on narrow viewports (single column) all three
cards stack vertically as expected.

* docs(changelog): Because-you-listened seed pool + 1080p layout polish (PR #493)

* docs(changelog): fold PR #493 refinements into the existing Because-you-listened entry

Drop the separate Changed section entry — the feature is in the same
1.46.0 release window as PR #489, so readers want a single description
of the final behaviour, not "added X, then changed X" for the same
release. PR reference becomes "PRs #489, #493".

-* New Home rail that surfaces albums **similar to one of your most-played artists** — Spotify-style "Because you listened to …" recommendations.
-* Anchor artist is rotated **round-robin** between Home opens through the top **8** entries in Most Played (so the rail does not get stuck on the same name). `getArtistInfo` returns up to **12** similar artists; the rail randomly samples **6** of them and surfaces **3** albums (one random per matching artist) that exist on your server.
-* Anchor rotation is **per-server**: switching servers keeps independent rotation state instead of aliasing one server's anchor id onto the next server's pool.
+* New Home rail that surfaces albums **similar to one of your favourite artists** — Spotify-style "Because you listened to …" recommendations.
+* Anchor pool round-robin merges **Most Played**, **Recently Played** and **Favorites** (deduped per artist), so the per-mount rotation lands on a different listening *mode* each visit instead of walking only the top-played list. Pool size **12** lets the cursor visit all three sources before wrapping. Within each anchor, `getArtistInfo` returns up to **12** similar artists; the rail randomly samples **6** of them and surfaces **3** albums (one random per matching artist) that exist on your server.
+* Anchor rotation is **per-server**: switching servers keeps independent rotation state instead of aliasing one server's anchor id onto the next server's pool. The rail also renders on fresh servers that have no frequent-play history yet, as long as they have starred or recently played items. Zero extra API calls — all three seed lists are already in the Home initial fetch.
+* **Responsive layout:** **3** cards in one row on 2K-class screens, **2** cards in one row at 1080p (the orphan third card on a second row is hidden via container query), and all **3** stacked vertically on truly narrow / mobile widths.
 * Toggleable in the Home customizer like every other rail; respects the existing performance flags ("Disable rail artwork", "Disable Home album rows").
