feat: 客户管理和项目管理模块完善更新接口

## 客户管理模块
- CustomerUpdateDTO: 客户更新DTO
- CustomerService: 新增updateCustomer方法
- CustomerServiceImpl: 实现客户更新逻辑
- CustomerController: 新增PUT /api/v1/customer/{id}接口

## 项目管理模块
- ProjectUpdateDTO: 项目更新DTO
- ProjectService: 新增updateProject方法
- ProjectServiceImpl: 实现项目更新逻辑
- ProjectController: 新增PUT /api/v1/project/{id}接口

## 功能特性
- 更新时检查编码唯一性（排除自身）
- 支持状态更新
- 自动记录更新人和更新时间
