refactor: 代码质量优化 + 安全修复 + 性能提升

P0 安全修复:
- 修复 DatabaseFieldAdder.java 硬编码密码 → 改为环境变量
- 修复 11 个文件空 catch 块 → 添加日志记录
- 修复 40 个文件 System.out → 改为 SLF4J Logger

P1 性能优化:
- 启用 Spring Boot Actuator 健康检查 (health/info/metrics)
- 为字典数据查询添加 @Cacheable 缓存

P2 测试:
- 添加 Convert 工具类单元测试 (10 个测试用例)
- 添加 spring-boot-starter-test 依赖

P3 版本升级:
- hutool: 5.8.35 → 5.8.36
- httpclient 5.x (跳过, 改动量大)

验证: 编译通过 / 测试通过
