Each of the 4 stage cards in the admin Library Scan section gains a
StageBadge in its header. The badge derives state via stageState()
from the existing ScanStatus payload — no new query, no schema
change. Active stage shows spinner + "Processing" in moss green;
done shows check + "Done" in moss green; pending and skipped show
muted text.
Card body now shows either the (possibly partial) numbers OR a
"Waiting for previous stage…" placeholder when the badge is
pending. The previous bottom-of-card "Pending…" / "Skipped."
fallback text disappears (the badge replaces it).
StageBadge.test.ts covers the four state renderings.
admin.test.ts adds one new case asserting the Processing badge
shows when scan.library is populated and in_flight: true. Existing
admin.test.ts assertions still pass (the default mock data has no
stage tallies + in_flight: false → all stages skipped, no Loader/
Check icons rendered).
