Share songs, albums, movies, shows, podcasts and audiobooks to chat as cards

A share message carries kind, title, subtitle, same-origin art and a hash-route
link, validated on the server. It counts as unread, reads as '🎵 Shared a song:
Title' in pushes and Notifications, and is found by search. In Chat a card opens
the item, or says it is not available when the recipient lacks that tab.
