fix: use mid price for initial adaptive CL sell instead of fixed breakeven floor

Check mid price first, place limit at market price (capped at mmSellPrice).
Only falls back to breakeven floor if mid price is below it.

Example: YES filled @ 70c, NO mid = 38c → sell @ 38c (not 30c breakeven)
This gives profit potential instead of always targeting breakeven.
