-- ==============================================================================
-- RailwaySystem 数据库 V2 增量脚本: 022_add_accommodation_lock_result.sql
-- 目标: 为 train_accommodation 增加 lock_result (门锁授权结果)
--   1. 新增列 lock_result SMALLINT NOT NULL DEFAULT 1
--      取值: 1 未授权 / 2 已授权 / 3 已过期，默认 1(未授权)
--   2. 新增字典类型 train_accommodation_lock_result 及其 3 个字典项
-- 适用数据库: KingbaseES V009R003C018 / PostgreSQL (schema: public)
-- 幂等性: ADD COLUMN IF NOT EXISTS + NOT EXISTS 判断，可重复执行
-- 说明: 仅新增列、列注释与字典数据，不涉及数据约束变更与业务逻辑调整
