fix(post-review): list part-support warnings in the post review

PartSupport findings counted toward the headline and the Post Anyway
checkbox but had no tile or list group, so an operator saw "1 warning"
with nothing to read and was likely to tick through a part that may tip
once cut free. A test now fails if any finding kind is left unlisted.
