feat: group unrepairable legacy items separately in catalog audit

After a repair attempt, items whose nitro/icon assets cannot be restored
from any source are reclassified from hard errors into a dedicated
'Unrepairable (legacy)' group (info), so a fully repaired catalog can
reach 0 errors while still listing exactly what is not restorable. Adds
an unrepairable summary count and a dedicated tab in the audit UI.
