Present replay 3D with the cursor and open Analyze on a remembered video

Replay left the 3D pane on the rest mesh or a sparse overlay, and Analyze skipped the setup dialog unless the file was re-picked. Live Run no longer starts a chain on a video path. Verified with Studio tests for flush, overlay mask, Analyze open, live-video refusal, and locales.
