fix: 修复 course.ts 中 http 对象未导入的问题

Browse Source 
- 添加 http 对象封装，支持 get/post/put/delete 方法
- 修复 submitCourse 和 rejectCourse 函数中 http.post 未导入的问题
- 确保课程包编辑页面的"保存"和"保存草稿"按钮能正常请求后端

同时包含之前的数据库外键修复：
- 新增 V39 迁移脚本删除外键约束
- 修改 V28 移除外键创建语句
- 增强 CourseCollectionService 应用层验证

-- 迁移 V39: 删除外键约束
-- 原因：MySQL 不允许修改被外键约束引用的列
-- 问题：V38 尝试为 course_collection.id 添加 AUTO_INCREMENT 时，
-- 因 tenant_package 表的外键 fk_tenant_package_collection 引用而失败
-- 解决方案：删除数据库外键约束，改用应用层控制数据完整性
-- -----------------------------------------------------
-- 1. 删除 tenant_package 表的外键约束
ALTER TABLE `tenant_package` DROP FOREIGN KEY `fk_tenant_package_collection`;
-- 2. 删除 course_collection_package 表的外键约束

ALTER TABLE `course_collection_package` DROP FOREIGN KEY `fk_collection_package_package`;
-- 3. 删除不再需要的外键索引（可选，提升写入性能）
