feat(migration): V8 业务答复口径落实——审批开关默认开启、撤试用期统一参数、经理基数开关、台账分摊唯一键

- #5/#7 答复默认开启：两审批开关 default 翻 1，插 10-19 生效行保时点历史
- #16 答复逐人维护：撤 probation.salary.basic（无业务消费点，月结已读 personnel.salary_standard）
- #12 答复参数化：新增 manager.personal.included（默认 0=不计入聚合基数）
- #1 答复分配绩效铺路：台账 uk 扩为 (receipt_id, calc_version, personnel_id) 支持分摊拆行
- schema_sync 解析器过滤 ADD CONSTRAINT 误捕获
