feat(course): reset student course progress (#671)

* feat(course): add reset student course progress action

Give course admins and tutors a destructive reset-progress flow on the
student people detail page. The backend clears learner progress for one
(courseId, memberId) pair in a single transaction while keeping the
groupmember enrolled, and logs an audit summary. The dashboard shows a
confirmation dialog with impact counts from analytics before deleting.

* fix(i18n): add localized reset progress strings for all locales

* fix(course): scope reset progress to course data only

Stop deleting org-level community questions and answers during course
progress reset. Fix course newsfeed deletion order so comments on a
student's posts are removed before the posts themselves. Restrict reset
to student members, move analytics loading to the person detail layout,
and rename impact copy to course newsfeed only.

* fix(course): address Greptile review on reset progress

Make progressImpact opt-in via includeProgressImpact query param so
analytics requests avoid extra DB work unless the reset dialog needs it.
Count only student-authored course newsfeed posts and comments in the
impact summary to avoid double-counting replies on the student's posts.
