Third admin page. Documents the severity stat cards (errors/warnings/
info, cards only appear when non-zero), the per-issue card fields, and
the three actions with their real semantics: Retry (per-item scanner
re-run — success closes the issue, failure surfaces the real error),
Retry all (sequential queue with done/total progress, deliberately not
a library-wide scan), Dismiss (warnings/info only, confirm-guarded;
errors cannot be dismissed). Links to scanning.md for the retry-vs-
library-scan distinction. Glossary gains Retry, Retry all, Dismiss.
