Fix enrollments report + add absence-by-trainer report with session filter

1. Enrollments by program: replace PostgreSQL-incompatible HAVING on alias with get()->filter()
2. New report "المتغيبون حسب المدرب": shows absent participants grouped by trainer, with min-absences filter (1/2/3/5 sessions), excludes suspended participants
3. Also fixes existing absentee report to exclude suspended via the new report variant
