Add demo trading executor and analysis scheduling (plan 3 C4)

- Executor reconciles each symbol to its desired orders: journaled ap{id}
  client ids, reduce-only quantity stop placed before entries, make-before-
  break stop moves, breakeven after TP1, orphan cancel, -2021 market close
- Plan lifecycle: proposed plans are adopted only if the position is
  unchanged; holding-mode plans may only tighten the stop
- Program rules: time stop, short-term invalidation close, long-term 4h
  review, reevaluate conditions, takeover of unmanaged positions
- Trigger and routine analysis scheduling with a 10 min gap, daily cap and
  bounded retries
- Plan endpoint and plan status, fills and countdowns on the trading page
