feat(home): Recently Played Albums gets a View-all full page

The rail's 'View all' opens a dedicated page listing the recently
played albums (the dedicated album history from the #567 fix, cap 24).
Built on the AwardAlbumsView skeleton stripped to essentials: fixed
header + windowed AlbumCollectionView wired per the new sampler
contract, scroll-restore, shared scrollbar. Works offline (local
history — the AppShell arm deliberately skips the offline gate) with
mixed-source rows routing through the existing open-album funnel
(qobuz/plex/local) and source-split artwork dispatch mirroring the
rail's. Full nav integration: NavEntry::RecentAlbums round-trips
through last_nav so view persistence restores it (a local JSON read —
cannot crash-loop), ADR-004 back button via the standard record +
navigate + flags shape. Zero new msgids — title, empty state and the
View-all link all reuse existing strings across the 8 locales.
