feat(pre-planting+mobile): 预种奖励在"我"页面展示

## 问题
预种奖励直接走 planting-service → wallet-service，绕过 reward-service，
导致前端"我"页面读 reward-service 的 summary/settleable 数据时看不到预种奖励。

## 方案
前端同时读 reward-service（正常认种）和 planting-service（预种），合并展示。

## 后端（planting-service）
- PrePlantingRewardEntryRepository: 新增 findByRecipientAccountSequence() 方法，
  按收款方账户查询预种奖励记录（注入 PrismaService 替代事务 client）
- PrePlantingController: 新增 GET /pre-planting/my-rewards 端点，
  返回当前用户作为收款方收到的预种奖励汇总+明细列表
  格式与 reward-service 的 settleable 对齐（id, rightType, usdtAmount, sourceOrderNo 等）

## 前端（Flutter mobile-app）
- PrePlantingService: 新增 getMyRewards() 方法 + PrePlantingMyRewards/PrePlantingRewardItem 数据类
- profile_page.dart: 并行调用 prePlantingService.getMyRewards()，
  将预种奖励转为 SettleableRewardItem 合并到可结算列表，
  summary.settleableUsdt 也加上预种金额
