fix: use taker fees (BG 0.06%, HL 0.045%) + threshold 0.25%

Browse Source 
All IOC market orders incur taker fees, not maker fees. Previous
makerFees (BG 0.02%, HL 0.015%) caused 0.10% threshold trades to
actually lose 0.11% per round trip.

Changes:
- scanner.go: makerFees → takerFees (BG 0.060, HL 0.045)
- dashboard.go: makerFees → takerFees
- types.go: makerFees → takerFees
- trader.go: makerFees → takerFees
- config.json: trade_threshold 0.1 → 0.25
