refactor(Orion-server): support MR -> multiple tasks, task -> multiple builds

[slow2342]

概要

本 PR 对 orion-server 的任务与构建关系进行了重构。
原先每个 task 只能绑定一个 build，现在一个 MR 可以关联多个 task，每个 task 也可以同时关联多个 build，以支持更灵活的调度与执行流程。

变更内容

• 数据库 schema 更新：
  • 拆分原有 tasks 表为 tasks 与 builds 两张表；
  • task 表只存任务信息，builds 表存 build_id 与输出文件等信息；
• 重构 ORM 与 SQL 查询，支持 task 与多个 build 的关联；
• 修改核心模块：
  • scheduler.rs、tasks.rs、api.rs 等，适配新的MR-Task-Build关系；
• 调整日志处理逻辑：
  • 确保能够正确关联多个 build 的输出；
• task_handler 接口调整：
  • 需要传入多个build
• tasks_handler 接口调整：
  • 返回格式变更，现在返回多个build，原有status字段移入build内

变更动机

• 支持单个 MR 下的多任务、多构建并行或增量执行；
• 为未来更复杂的调度和工作流扩展做好准备；
• 数据模型更贴近实际业务需求，提升灵活性。

注意事项

• 部署时需要执行数据库迁移；
• task_handler 接口变更，需要 mege 端适配。

Pull Request Overview

This PR refactors the orion-server to support a many-to-many relationship between MRs, tasks, and builds, replacing the previous one-to-one task-build relationship. The changes enable more flexible build scheduling and execution workflows by allowing multiple tasks per MR and multiple builds per task.

• Database schema restructured to separate tasks and builds into distinct tables with proper foreign key relationships
• API endpoints updated to handle multiple builds per task with new response formats
• Task scheduling logic modified to support queuing and dispatching multiple builds
