Add quick button to mark unexpected ports as expected

Allow users to add ports to expected list directly from scan results page
instead of navigating through site config pages. The button appears next
to unexpected ports and updates the site IP configuration via the API.

- Add site_id and site_ip_id to scan result data for linking to config
- Add "Mark Expected" button next to unexpected ports in scan detail view
- Implement markPortExpected() JS function to update site IP settings
