feat(fediverse): star = like via your own fediverse account (server-only input)
The post heart is now a star that lets any visitor like the post from their own
fediverse account: click -> enter just your server (e.g. mastodon.social) -> bounce
to your server's authorize_interaction. No full @handle needed (your server knows
who you are). Count shows incoming fediverse likes. Reuses the remote-interaction
popover; placeholder simplified to the server.
