feat(news): auto-push published news to the in-game Town Cryer News gump (2.1)

Phase 4: sync the site's published news posts into the Protocol 2.1 News gump.

- uoLinkClient.postNews / deleteNews.
- utils/newsGump.js — a STATE SYNC (not a one-shot announce leg): an article
  stays in the gump while its post is published news and is pulled when it leaves
  that state. buildArticle renders a compact gump-HTML block (centred title +
  plain-text excerpt — the gump supports only a small HTML subset) with a
  "more info" link to /site/news and an optional gump image from the
  `news_gump_image` setting. Every call is best-effort / never-throws.
- Hooked into the posts pipeline alongside the existing announce enqueue:
  syncPost on create/update/publish (fresh publish announces; edits refresh
  silently; leaving published-news pulls the article), removePost on delete.
- reassertAll() runs in uoLinkSocket.backfill on every WS (re)connect —
  reconciles the gump to our source of truth and recovers any article whose
  original live push failed (silent, so a reconnect never re-proclaims old news).

Server 185/185, swagger regenerated. Refs .plans/protocol2-integration.md (Phase 4).
