班级查询按“考试场次”合并，显示为“分散至 N 个考场”，不再生成大量重复卡片。[后端实现 (line 416)](E:/jiaowu/src/Jiaowu.Api/Infrastructure/Timetables/TimetableDataService.cs:416)

学生登录后只显示本人座位对应的考场，同时修复混排考场可能带出其他课程的问题。[筛选逻辑 (line 561)](E:/jiaowu/src/Jiaowu.Api/Infrastructure/Timetables/TimetableDataService.cs:561)
多考场卡片提示学生登录查看本人考场及监考教师。[前端展示 (line 1122)](E:/jiaowu/web/src/views/TimetableView.vue:1122)
教室课表、监考教师课表仍按具体考场显示，不受合并影响。
已增加班级合并和学生精准考场回归测试。[测试 (line 183)](E:/jiaowu/tests/Jiaowu.Api.Tests/ExamArrangementServiceTests.cs:183)
