feat: MM adaptive cut-loss with profit floor

When one leg fills, instead of immediately market-selling the unfilled
leg, enter a continuous monitoring loop that:
- Places a limit sell only when price >= minAdaptivePrice floor
  (floor = mmAdaptiveMinCombined - filledLegPrice, default combined 1.20)
- Chases price upward (>2% improvement → re-place limit higher)
- Cancels limit on dip >5% or below floor, then waits for recovery
- Market-sells only as last resort when CL time is reached

New config: MM_ADAPTIVE_CL (toggle), MM_ADAPTIVE_MIN_COMBINED (floor),
MM_ADAPTIVE_MONITOR_SEC (poll interval). Legacy immediate market-sell
path preserved when MM_ADAPTIVE_CL=false.
