Implement AI translation, attack paths, and PDF reports - Advanced features phase

Features added:
- AI Finding Translation endpoints (POST /findings/{id}/ai-translate)
- AI Security Coach endpoint (POST /findings/{id}/ai-question)
- Attack Path visualization generation (POST /attack-paths/{id}/generate, GET /attack-paths/{id})
- Mock AI implementations for demo mode (no API keys required)
- PDF Report generation and download endpoints
- Report snapshot feature for on-demand PDF generation

Technical improvements:
- Mock translation system for findings and attack paths
- Async task-based AI processing
- Graph-based attack path with nodes and edges
- Professional HTML-to-PDF conversion with WeasyPrint
- Jinja2 templating for report generation

Database updates:
- AttackPath table integrated with mock narrative generation
- AI fields populated via async tasks

Testing:
- All E2E tests verified passing (login, dashboard, findings, all roles)
- AI endpoints tested and working with mock data
- PDF report generation produces valid 18KB+ documents
- Attack path generation creates proper graph structures
