The read-only embed renderer mounts a Tiptap EditorProvider with the looked-up
content, but Tiptap consumes the `content` option only at initial mount. After
Refresh busted the lookup cache and re-fetched fresh content, the new content
prop never reached the sub-editor, so the embed appeared not to update at all.
Key PageEmbedContent on result.sourceUpdatedAt (the source page's updatedAt,
already returned by the lookup and bumped on every persisted content change) so
the component and its EditorProvider remount and apply the refreshed content
when the source changes.
Note: server-side freshness vs. live collab edits is bounded by the 10s persist
debounce (collaboration.gateway.ts) — that separate limitation stays documented
in #40 and is out of scope here; this commit fixes the client never re-rendering.
