no price floor: min_price 0.01 → 0 (both books), cap stays 0.95

Browse Source 
User call 2026-07-13 after a big 0.001 longshot was floor-blocked (the
same band class that blocked the 16x Hive copy at 0.05). Executor's
protected prices now round to 4dp and scale with the price — the old 2dp
rounding zeroed the bound on sub-penny books (BUY never bounds below the
quoted cross; SELL never above the quoted bid; verified at 0.001/0.002).
