feat(discover): add get_dynamic_suggest_full carrying track_to_analysed

Tauri's DailyQ/WeeklyQ /dynamic/suggest seeds a track_to_analysed payload
(~9 resolved {track_id,artist_id,genre_id,label_id} tuples) for the PRIMARY
mix algorithm; the empty-analysis call is only its fallback. The Slint port
only ever sent the empty-analysis path. Add a TrackToAnalyse model
(qbz-models) and a get_dynamic_suggest_full method on the qobuz client and
qbz-core that carries the payload; the existing get_dynamic_suggest now
delegates with an empty analysis (behaviour unchanged). Plumbing only — the
mix.rs build of the analysis tuples + the two-call fallback lands next (a2).
