Fix JSONID type conversions for yandex-music-api-go v0.0.0-20261018072517-d0173f795d2a

The new library version uses models.JSONID (custom string type) for ID
fields instead of plain string. Convert to string where IDs are passed
to functions expecting string or compared with string values.

Affected: client.go (GetTrackInfoWithPosition), downloader.go
(track.ID usage), monitor.go (track.ID, album.ID usage), storage.go
(album/track ID assignment).
