助教工资计算任务
功能说明：
以"助教+月份"为粒度，计算月度工资明细
数据来源：
- dws_assistant_monthly_summary: 月度业绩汇总
- dws_assistant_recharge_commission: 充值提成（Excel导入）
- cfg_performance_tier: 绩效档位配置
- cfg_assistant_level_price: 等级定价配置
- cfg_bonus_rules: 奖金规则配置
目标表：
billiards_dws.dws_assistant_salary_calc
更新策略：
- 更新频率：月初计算上月工资
- 幂等方式：delete-before-insert（按月份）
业务规则（来自DWS数据库处理需求.md）：
- 基础课收入 = 基础课小时数 × (客户支付价格 - 专业课抽成)
例：中级助教基础课170小时，3档 = 170 × (108 - 13) = 16,150元
- 附加课收入 = 附加课小时数 × 附加课价格 × (1 - 打赏课抽成比例)
例：附加课15小时，3档 = 15 × 190 × (1 - 0.35) = 1,852.5元
- 冲刺奖金：H>=190:300, H>=220:800（不累计，取最高档）
- Top3奖金：1st:1000, 2nd:600, 3rd:400（并列都算）
- 充值提成：来自dws_assistant_recharge_commission
- SCD2口径：等级定价使用月份对应的历史值
