feat(pre-planting): Mobile App 预种计划 Service 层
[2026-02-17] 新增预种计划的 Flutter 端 API 服务层： 1. pre_planting_service.dart（新增） - PrePlantingService：预种 API 调用（配置/资格/持仓/订单/合并/签约） - 数据模型：PrePlantingPosition、PrePlantingOrder、PrePlantingMerge 等 - 与现有 PlantingService 完全独立 2. api_endpoints.dart（+10 行） - 添加 /pre-planting/* 端点常量 3. injection_container.dart（+9 行） - 注册 prePlantingServiceProvider Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
