Setting MODE=live alone no longer starts trading. check_live_ready requires an active risk limit, MAX_POSITION_PCT < 1.0, LIVE_CONFIRMATION exactly "I UNDERSTAND THE RISK", a minimum balance, and exchange credentials. Enforced in Runtime.start_many (both start paths) and surfaced at GET /api/live-check; the dashboard shows a banner and blocks the start buttons. Adds tests.
