Fix repeat ownership and close out capture evidence

Start each repeat after its own manifest entry, refuse packets from a restarted
or stopped camera, keep a simulated repeat from reading as recorded evidence,
and decide completeness from the writer report. Add the operator summary (four
files plus an atomic pointer) and read-only video review of a hold window.

Verified with the full Autocal suite (567 passed), the shared recorder/playback
files (57 passed), the lint gate and the documentation gate; the two pre-existing
panel_check layout failures also fail on a clean HEAD worktree.
