feat: read the profile's topics from Studio, and add working-copy deletion

Two things an author could not control from Studio.

The profile's "주요 관심 주제" was four strings in the JSX. Creating or removing
a topic in Studio changed nothing, and correcting the list meant a rebuild and
a redeploy. It now renders the published topic list. The old literal opened
with "Backend Architecture", which no record in the catalogue actually carries
— the profile was advertising a topic that did not exist, and nothing could
have caught that while the list lived in the markup.

The working-copy list gained a delete control. It routes by kind because the
contract and the storage both do: Case and Reference share one table split by
type, Question is its own. Decision has no delete — its lifecycle is accept,
reject, supersede, which records what happened rather than erasing it — so the
control does not appear for it.

The list summary carries no version, so deletion reads the working copy first
and uses the version it finds. A stale version from a list left open should
fail as a conflict, not delete whatever is there now.
