fix(gis): #21 修复PM退回问题 - 完整测试和真实集成

🔧 修复内容：
- ✅ 补充完整单元测试：GisServiceTest + GisControllerTest
- ✅ 实现真实GeoServer/PostGIS集成，移除Mock数据
- ✅ 添加完整的异常处理：GisExceptionHandler + GisException
- ✅ 创建PostGIS数据库初始化脚本
- ✅ 更新Controller支持配置和健康检查

📝 详细改进：
- GisServiceImpl：连接真实数据库和GeoServer REST API
- GisController：增强错误处理和配置管理
- 新增exception包处理所有GIS相关异常
- test包包含Service和Controller层的完整测试覆盖
- scripts/init-postgis.sql：完整的PostGIS表结构创建

🚀 解决PM退回的所有问题：
1. 测试验证 ✅ - 添加了完整的单元测试
2. 代码质量 ✅ - 移除硬编码，实现真实集成
3. 异常处理 ✅ - 全局异常处理器

请审核。
