Phase 5 Batch 5 Task 5.18: Report Generator PDF-Support & Druck-Funktionen

- Installed WeasyPrint 69.0 for PDF generation
- Created 5 Jinja2 HTML templates: contact_list, calendar_week, calendar_month, company_list, audit_log
- All templates: A4 landscape, print-optimized CSS (@media print, page margins)
- Extended output_format in schemas.py: added pdf and print
- Created pdf_generator.py: Jinja2 + WeasyPrint pipeline with preset support
- Modified routes.py: PDF/print generation, preset endpoints (/presets, /presets/generate)
- Added RBAC (require_permission) to all report endpoints
- Generate endpoints return StreamingResponse (file download) directly
- 7 backend tests: presets listing, PDF/CSV generation, template CRUD, RBAC
