feat(award): backend V2 commands for /award/page and /award/getAlbums

Backend plumbing for Phase 3 AwardView. New endpoints:
- v2_get_award_page(awardId)       → hero + categorized releases
- v2_get_award_albums(awardId, …)  → paginated album list

Mirrors Android's AwardDto shape (id, name, image, awarded_at,
magazine, releases, playlists). Follows the label/page pattern for
signing and error handling. Deserializer accepts the V2 generic
{has_more, items} envelope as well as the legacy search-style
{albums: {items, total}} in case Qobuz swaps shapes per account.
