feat: add Onko-Intensiv and Galle-Schild report types

Adds report_type support across the full stack:
- Backend: REPORT_TYPES mapping, fallgruppen filter in all 5 sheet
  calculations, dynamic Excel columns, report_type DB column with
  Alembic migration 007
- Frontend: report type dropdown in generation form, type column in
  reports table, dynamic fallgruppen in ReportViewer
