Fix scan output file paths and improve notification system

- Save JSON/HTML/ZIP paths to database when scans complete
- Remove orphaned scan-config-id reference causing JS errors
- Add showAlert function to scan_detail.html and scans.html
- Increase notification z-index to 9999 for modal visibility
- Replace inline alert creation with consistent toast notifications
