fix(ghost-detector): vendor-category filter on PG source path + scrub poisoned flagged set

scripts/scan-ghost-layer.js:
- fetchPgTargets() now applies VENDOR_CATS filter (same set used by fetchJsonTargets).
  Previously only the JSON-source path skipped vendor SKUs; the PG path scanned
  every is_published=TRUE row with a local_path, which fed Gemini Vision a bunch
  of real vendor catalog images. The detector flagged 8 of them as ghost-layer
  false positives. A downstream cleanup unpublished those 8 vendor SKUs on prod
  (Maya Romanoff, Ralph Lauren, Phillipe Romano, Koroseal, Coordonné, Malibu,
  Glitter Walls, Graduate Collection). Restored manually 2026-05-24.

data/ghost-scan-flagged.jsonl:
- scrubbed 3 vendor-category entries from the local flagged set so the bulk-delete
  UI on prod can't pick them up by accident. Prod copy scrubbed too.
