feat(fingerprints): Add database indexes and expand test data generation

- Add database indexes on 'link' field in FingersFingerprint model for improved query performance
- Add database index on 'author' field in FingerPrintHubFingerprint model for filtering optimization
- Expand test data generation to include Fingers, FingerPrintHub, and ARL fingerprint types
- Add comprehensive fingerprint data generation methods with realistic templates and patterns
- Update test data cleanup to include all fingerprint table types
- Add i18n translations for fingerprint-related UI components and labels
- Optimize route prefetching hook for better performance
- Improve fingerprint data table columns and vulnerability columns display consistencyzxc
