refactor(flight-schd): 按现场 11g 约束将运营航班存储改为宽表 (ACM2-28 修订)

现场环境仅提供 Oracle 11g（无任何 JSON 能力），废除 FLTR_JSON JSONB 整文档存储：

- V1.1.0 迁移重写：FLIGHT_SCHD 改为一行一航班宽表（SCHD.FLTR 标量字段列 +
  1:N 明细集合序列化文本列），SCHD_GEN.FLIDS_JSON 展开为 SCHD_GEN_FLID(FDAY, FLID)；
  已应用过旧版迁移的环境需重建 schema 重放
- 契约层：FlightChange/Handler 在线视图改为字段集映射（与 legacy flightInfo
  hash 同构），仓储白名单拒绝未知字段；增量写=字段级合并（hmset 同语义），
  快照=整体替换
- 事件载荷：快照投递与投影重建经 FlightFieldsJson 确定性序列化（键序稳定）
- 影子对拍：FlightStoreDiffTool 改为 PG 宽表列值 vs legacy FLTR JSON 逐字段
  归一化比对，新增嵌套集合比对用例
- 测试：61 用例全绿（不变量门槛 1/2/3、UTC 方言、真实 PG 方言集成、清场五场景）
- 文档：decision-flight-state.md 追加 §8 修订记录（不改写定案历史），design.md 表说明同步

11g 方言移植（ON CONFLICT→MERGE、advisory lock 替代、Flyway/驱动矩阵）、
集合列升子表、类型化列提升等未尽事项另立 Plane issue 跟踪。
