docs(byo-ui): correct toolbar ids and comment scrollTo scope

Two factual fixes flagged in PR #3034 review:

- toolbar-and-commands.mdx: the built-in command id table listed
  several ids that aren't on PublicToolbarItemId. strike →
  strikethrough, color → text-color, highlight → highlight-color,
  and the entire 'Block' row (heading-1/-2/-3, paragraph) is dropped
  because no block-level commands exist on this surface today.
  Replaced the table with the actual id set grouped by domain.
- comments.mdx: the trade-off note claimed ui.comments.scrollTo is
  story-aware. CommentAddress is body-scoped in the contract — only
  TrackedChangeAddress carries a story field — so the call doesn't
  navigate to header/footer/note comments. Replaced with an honest
  description and pointer to ui.viewport.scrollIntoView for non-body
  cases.

+Scrolls the editor viewport to the comment's anchor. Body-scoped today: the comment-address contract carries no `story` field, so a comment anchored in a header, footer, or note doesn't navigate through this call. For now, scroll those manually via `ui.viewport.scrollIntoView({ target: ... })` once you've resolved the right address yourself.
