chore(router): remove the CHAINDBG probe — the curated-order path is browser-verified

The debug print served its purpose: the stale-binary native-order render
was an artifact of an incomplete rebuild, not code. Fresh container
resolves view_settings.chain_order and the chain plays in the curated
order (newest-first verified on a 23-episode feed with a date tie at the
tail, handled by the position tie-break).
