URL Auto-Detector and Clickable Rendering for List Fields — make socials, helpful_links, and official_updates_index_urls open-in-tab links instead of opaque JSON

Three of the most operationally important Augment-It fields are list-shaped — `socials`, `helpful_links`, `official_updates_index_urls`. Each is either a `string[]` or an `Array<{ url: string, ...metadata }>`. Today's field renderer (shipped earlier today in commit `2004770`) stringifies them as JSON, which is legible but not actionable — the operator can't click through to verify the link works, and the secondary metadata (display_name, confidence, label, note) clutters the visual scan. This plan adds a shape-detecting URL extractor (`formatFieldValue` becomes pluggable) and renders any field whose value is a URL — scalar string, array of strings, or array of objects with a `url` key — as a list of clickable `<a target="_blank" rel="noopener">` links, one per URL, with the auxiliary metadata dropped from the rendered view. The forcing function is the next bundle's hard dependency: it fires only against rows whose `socials`, `helpful_links`, and `official_updates_index_urls` already carry ≥1 URL, so the operator must be able to skim Record Collector and visually confirm 'yes there's a link here, and yes it's the right one' fast. Closes the audit side of [[OfficialPulse-URLs-Appear-as-Junk-in-Promoted-Versions]] — the curation/remove side stays as a sibling follow-up.
