Fix Bug #435: 门诊手术安排：编辑弹窗中"费用类别"字段数据未回显

根因：OpSchedule 实体缺少 feeType 字段，创建手术安排时费用类别未被持久化到数据库。编辑时详情查询通过复杂 JOIN 链（adm_encounter → adm_account → fin_contract）计算 feeType，链断裂时返回 null。

修复方案：
1. OpSchedule.java 新增 feeType 字段，使创建时费用类别持久化到 op_schedule.fee_type
2. SurgicalScheduleAppMapper.xml 详情查询改用 os.fee_type，移除不可靠的 JOIN 链
3. OpScheduleDto.java 移除重复的 feeType 声明（现从父类继承）
4. 新增 DDL 迁移脚本添加 fee_type 列
