feat: 新建课程作业模块（基于校园公告模板），实现 v1 教师端与 v2 学生/家长端

以 CampusAnnouncement 为模板建立课程作业模块，重命名标识符与文案（notice→homework、公告→作业），并保留其顶栏/左栏外壳，按课程作业业务重搭数据模型与页面。 - mock(src/assets/mock/homeworkapi.ts)：作业化数据模型（学科/截止/提交方式/流程状态），班级花名册→学生个体提交记录与批改（确定性分布），端点 List/SendList/Submissions/ SubmissionDetail/Grade/Remind/Statis 等；左栏菜单按角色返回。 - v1 教师端：布置作业(新增学科/截止/提交方式)、我布置的(状态标签+提交/批改进度)、提交情况(Submissions，含内联批改)、批改中心(Grade 逐份批改)、作业统计(成绩分布+进度)。 - v2 学生/家长端(端分离)：SetRole + viewerRole 切换身份；StudentHomeworks.vue 承担今日作业/待订正(学生可提交/重交)与孩子作业(家长只读+提醒)；新增 MyHomeworks/Submit/ MySubmission/ParentNudge 接口与类型。 - 类型与 api 模块同步；dev:mock 三角色 curl 端到端验证通过。
