/album/get returns award.awarded_at as a Unix timestamp integer while
/discover/index returns it as a YYYY-MM-DD string — our struct only
accepted String, so /album/get started failing with
'invalid type: integer `…`, expected a string' as soon as awards were
added to Album in Phase 2. Every 'Load album' call broke.
Adds a custom deserializer that accepts both shapes and normalizes to
String downstream. Applied in both qbz-models (V2) and src-tauri legacy
api::models for symmetry.
