Make the cached analysis views reachable over a recording

Replay moved the cursor onto the result's timeline, so the recording's own
picture was not offered at all and ``use_recording()`` had no caller. Adopting a
result now keeps the cursor on the recording, opens the panel on a derived view,
and serves scrubs, playback and display changes from the cache (Part B §9).
Verified: apps/studio 455 items / 0 failed / 18 skipped, shared 427 / 0 / 1,
autocal 358, ui_check 628 checks / 0 failures, lint gate clean.
