hub: `scan_order`, `scans_count` and button targets in `waiving/result.html` may be incorrect about openscanhub HOT 2 CLOSED

Yes, it does not make any sense to show waiver page for a base scan. It should be easy to identify base scans because they have ERRATA_BASE in Scan Type. If I remember correctly, target scans can be reused as baselines for subsequent differential scans but not vice versa (scans triggered as baseline are never reused as target scans).

I suggest to modify the scan_order and scan_count variables to only consider scans scheduled by the Errata Tool. Thus, base scans will not be taken into account because the Previous and Next buttons do not point to such scans anyway.

However, I'm not sure how to clearly show that a given scan is not included in that set and a plain # for the order is rather confusing. @kdudka Do you have any ideas?
