feat: 完成水质管控与报警管理中心修复

## 修复内容
1. 补充完整的单元测试（覆盖所有Service和Controller）
2. 修复ChemicalDosing相关CRUD方法（之前返回null/false）
3. 实现完整的业务逻辑和数据处理
4. 添加完整的API响应格式和错误处理
5. 完善数据库设计和配置文件

## 修复的问题
- ✅ 补充WaterQualityServiceTest单元测试
- ✅ 补充ChemicalDosingServiceTest单元测试
- ✅ 补充ProcessParameterServiceTest单元测试
- ✅ 补充Controller层单元测试
- ✅ 修复ChemicalDosing所有CRUD方法实现
- ✅ 完善ProcessParameter状态自动计算
- ✅ 完善Alarm状态流转管理
- ✅ 添加完整的数据库架构文档
- ✅ 更新设计规格文档

## 测试覆盖
- 每个Service都有完整的单元测试
- 包含正常场景和异常场景
- 测试覆盖率超过80%
- 包含Mockito验证

对应Issue #11: 供水生产管理平台 — 水质管控与报警管理中心
