feat(system): 新增岗位角色与计提参数四表及 V3 迁移

- business_roles/param_definitions/param_change_batches/param_values 四表 + 种子(3 内置岗位/16 参数定义/19 版本条目/初始批次 P20260101-00)
- 双轨迁移:Alembic bfbda9c3191d + db/migration/V3 导出 + init-dev.sql 同步(schema_sync 校验通过)
- 参数值以 Fraction 可解析字符串存储(4/360 禁 0.011111);企业户 2‰→3‰ 双种子支持按到账日回溯

"""计提参数模型:定义、变更批次与版本条目。
存储设计(M1 评审定稿):
- 参数值按**生效日期时点化**存储(逐项版本条目,append-only),核算按业务
日期回溯取值(对照表 #11:按回款到账日匹配参数版本),禁读「当前值」算历史
- 「版本」由变更批次承载:一次保存 = 一个批次 = 一条变更记录;条目逐项留痕
(旧值/新值),满足 #28 版本管理与留痕(需规 2.3.1 四)
- 值一律为 Fraction 可解析字符串(如 "4/360",禁 0.011111),解析不经 float
- **不设 (param_id, dimension_value, effective_date) 唯一键**:同日多次修正
是合法留痕,解析取 (effective_date, id) 最新一条;唯一键会把同日二次变更
逼成覆盖写、丢失中间值
- 批次与条目均为 append-only(仅 create_time、无 update_time,同 login_logs
先例):带 ON UPDATE 的列会让「未改也被刷新」造成留痕假象
