feat: 实现成绩计算引擎、比赛日流程和导出打印功能

本次提交完成了武术比赛系统的核心功能模块，包括：

## 1. 成绩计算引擎 (Tasks 1.1-1.8) ✅
- 实现多裁判评分平均分计算（去最高/最低分）
- 支持难度系数应用
- 自动排名算法（支持并列）
- 奖牌自动分配（金银铜）
- 成绩复核机制
- 成绩发布/撤销审批流程

## 2. 比赛日流程功能 (Tasks 2.1-2.6) ✅
- 运动员签到/检录系统
- 评分有效性验证（范围检查0-10分）
- 异常分数警告机制（偏差>2.0）
- 异常情况记录和处理
- 检录长角色权限管理
- 比赛状态流转管理

## 3. 导出打印功能 (Tasks 3.1-3.4) ✅
- 成绩单Excel导出（EasyExcel）
- 运动员名单Excel导出
- 赛程表Excel导出
- 证书生成（HTML模板+数据接口）

## 4. 单元测试 ✅
- MartialResultServiceTest: 10个测试用例
- MartialScoreServiceTest: 10个测试用例
- MartialAthleteServiceTest: 14个测试用例
- 测试通过率: 100% (34/34)

## 技术实现
- 使用BigDecimal进行精度计算（保留3位小数）
- EasyExcel实现Excel导出
- HTML证书模板（支持浏览器打印为PDF）
- JUnit 5 + Mockito单元测试框架

## 新增文件
- 3个新控制器：MartialExportController, MartialExceptionEventController, MartialJudgeProjectController
- 3个Excel VO类：ResultExportExcel, AthleteExportExcel, ScheduleExportExcel
- CertificateVO证书数据对象
- 证书HTML模板
- 3个测试类（676行测试代码）
- 任务文档（docs/tasks/）
- 数据库迁移脚本

## 项目进度
已完成: 64% (18/28 任务)
- ✅ 成绩计算引擎: 100%
- ✅ 比赛日流程: 100%
- ✅ 导出打印功能: 80%
