选课批次可指定多个适用年级；留空兼容原有“全部年级”。 新增可选的“最多课程门数”，与原有学分上限并行。 年级、门数限制统一作用于学生可见批次、自主选课、候补、管理员代选和自动递补。 普通候选名单遵守年级及行政班范围；强制选课可绕过业务限制，但仍严格遵守管理员学院权限。 管理页面会展示“2026 级 · 最多 6 门 · 最多 30 学分”，名单和候补列表也增加年级列。 新增 MySQL 迁移：[CourseSelectionGradeLimits.cs](E:/jiaowu/src/Jiaowu.Api/Infrastructure/Persistence/Migrations/MySql/20260726180000_CourseSelectionGradeLimits.cs)。
