feat: 添加曝光回流收益 SQL (v1~v4) 及 AB 效果分析任务

- table_gen: 曝光回流 B+C 多跳计算 v1~v3，v4 新增 D 链（session 内后续曝光传播）
- table_gen: 曝光基础表建表 SQL
- AB效果: 推荐 AB 实时/天级效果、对比对照组、分小时/分seq/含多跳等任务 SQL 及配置

+-- 曝光回流收益计算 (B + C 多跳版)
+-- 数学公式:
+--   B_i      = 不换视频回流人数（用 rootshareid 计算）
+--   C_1(i)   = Σ B_j, j 在 E_i 回流用户的 session 中（1跳）
+--   C_2(i)   = Σ B_k, k 在 C_1 涉及曝光的回流用户 session 中（2跳）
+--   C_3(i)   = 同理（3跳）
+--   V_total  = B + C_1 + C_2 + C_3
+--
+-- 相比递推版:
+--   1. 去掉 D（session内累积），避免指数级膨胀
+--   2. 每层 C 独立计算，不依赖上一层结果
+--   3. CTE 从 ~18 个减到 ~12 个
