feat: interactive network map, IOC highlighting, AUP hunt selector, type filters

- NetworkMap: hunt-scoped force-directed graph with click-to-inspect popover
- NetworkMap: zoom/pan (wheel, drag, buttons), viewport transform
- NetworkMap: clickable IP/Host/Domain/URL legend chips to filter node types
- NetworkMap: brighter colors, 20% smaller nodes
- DatasetViewer: IOC columns highlighted with colored headers + cell tinting
- AUPScanner: hunt dropdown replacing dataset checkboxes, auto-select all
- Rename 'Social Media (Personal)' theme to 'Social Media' with DB migration
- Fix /api/hunts timeout: Dataset.rows lazy='noload' (was selectin cascade)
- Add OS column mapping to normalizer
- Full backend services, DB models, alembic migrations, new routes
- New components: Dashboard, HuntManager, FileUpload, NetworkMap, etc.
- Docker Compose deployment with nginx reverse proxy
