Add NauCourseFilter model and course_published signal handler to mirror enrollment/certificate filter settings (other_course_settings) into MySQL, so nau-database-exporter can expose them in Looker Studio without MongoDB access. Includes backfill management command and unit tests.

Course filters for analytics
Summary
This change mirrors enrollment and certificate filter flags from MongoDB (
other_course_settings) into a new MySQL table whenever a course is published in Studio, so nau-database-exporter can expose them in Looker Studio without connecting to MongoDB.Related context: NAU technical proposal / dashboard work (e.g. fccn/nau-technical#635, customer requirement: course filters visible in analytics).
Problem
Filter settings such as domain-based enrollment, NIF requirement, and Portuguese citizen card for certificates live only in MongoDB. The existing exporter reads MySQL only, so dashboards cannot tell which courses are effectively restricted for all learners.
Solution
NauCourseFilter:course_id,filter_type, timestamps;unique_togetheron(course_id, filter_type); one row per active filter.SignalHandler.course_publishedreads normalizedother_course_settings, creates missing rows, deletes rows for filters no longer active. Errors are logged and never block publishing.filter_enrollment_by_domain_list,filter_enrollment_require_nif,certificate_require_portuguese_citizen_card. Override viaNAU_COURSE_FILTER_KEYSfor future filters.sync_course_filters(CMS) for all courses, a single course (--course-id), or resume (--index).Deployment notes
0012_naucoursefilter.python manage.py cms sync_course_filtersonce to backfill historical courses (optionally chunked with--index).NauCourseFilterand add the desired boolean or denormalized columns for Looker Studio.
