Corpus adds don't fetch metadata — and the row gives no cue either way, and there's no inspector to see or fix it

Adding a corpus item to New America raised the question 'did it fetch the metadata?' — and the honest answer is no, and nothing on the row would tell you either way. The ➕ path writes url/kind/domain and stops; the Jina metadata fetch we already run for domain-corpus sources never fires for entity corpus.
