fix: standardize terminology — 排课 (clazz) not 课程 (course)

"排课" = scheduled class instance, "课程" = course content/curriculum.
All 21 instances of incorrect usage were in clazz/tongzhi/user-settings
contexts where the underlying data is a clazz (clazz_id, clazz_name,
is_repeat), not a course.

Affected files: clazz/index.vue (10), tongzhi/index.vue (4),
tongzhi/detail.vue (3), store/clazz.ts (3), user-settings.vue (1).
