fix(album): use dedicated tolerant AlbumAward struct instead of mutating PageArtistAward

Previous attempt loosened PageArtistAward (id u64 -> Option<u64>,
awarded_at custom deserializer) to accept /album/get's inconsistent
award shape. That rippled into /artist/page consumers, which the user
rightly called out ('no eliminar lo que ya funcionaba, adaptar pues').

Restores PageArtistAward to its original shape (id: u64, name: String,
awarded_at: Option<String>) and introduces a parallel AlbumAward type
used only on DiscoverAlbum and Album. AlbumAward tolerates missing id,
accepts awarded_at as int or string, and never fails deserialization
of the parent payload. /artist/page keeps its strict contract.
