feat(mobile): queue track reactions made offline and sync on reconnect (M5)

Likes and dislikes without a network are kept in a pending_reactions
table (last reaction per track wins) and sent when the connection
returns, instead of being rolled back. Downloaded track DTOs pick up the
new reaction so the offline wave and Downloads reflect it.
