fix: get_pay_fee 返回 fee_rate 而非 fee_rate*amount，修复双重乘法

Browse Source 
get_pay_fee() 返回 fee_rate*amount，但 create_payment()
又把返回值当 feerate 传给 new_log()，new_log() 内部又乘
一次 amount，导致 pay_fee = fee_rate * amount²。

修复：
- get_pay_fee() 改为只返回 fee_rate
- create_payment() 自己计算 fee = feerate * amount
- new_log() 传 feerate 而非 fee
