Post Likes

1// Post likes over REST — the twin of app/wix/blog/post-likes.ts. Same exports, same DTOs; the FQDN,
2// query, and body come from posts-core. Every call runs as the calling identity (member or the
3// anonymous visitor the token stands for), so all three are CLIENT-ONLY — in a port, never from a
4// process-wide token. Porting: keep the paths, keep the bodies.
