feat(open-api): 新增对外开放接口及项目日报同步功能

- 新增项目日报表及其防重唯一索引，支持外部系统同步日报数据
- 添加项目日报实体类及对应 Mapper 和 XML 配置
- 新增对外开放接口控制器 OpenApiController，实现项目列表查询及日报同步接口
- 实现 OpenApiService 服务及其实现类，包含用户项目查询和日报防重同步逻辑
- 扩展 ProjectMapper，支持根据用户名查询用户关联项目列表
- 配置 SaToken 过滤白名单，放行 /api/open/** 路径无登录验证
- 引入 spring-boot-starter-validation 依赖，支持请求参数校验
- 创建数据传输对象 DailyReportSyncDTO，带参数校验注解
- 日志记录和异常处理增强，保证数据同步和查询的健壮性
