INFO inspector — redesign

A cleaner INFO section that gives every selection a strong identity header (accent bar + name + kind chip), groups metadata under soft subheadings instead of bare rows and full-bleed dividers, treats long paths as a copyable inset, and collapses status into one pill. It also adds the two new contexts: click empty canvas → the JOB; click a GROUP box → the group. Scaffold is hand-drawn; the buttons/info-icons are the real components.
