Fix Kiwix status badges to reflect full pipeline state

Status was showing COMPLETE after ZIM extraction finished, even when
documents were still queued for enrichment/embedding. Now computes
effective_status by checking actual pipeline state per-source:

- DETECTED: ingest not enabled (gray)
- EXTRACTING: ZIM processor running (blue)
- PROCESSING: extracted but docs still in enricher/embedder queue (amber)
- COMPLETE: all docs fully enriched and embedded in Qdrant (green)

Also fixed _build_kiwix_sources pipeline query to filter by category
per-source instead of returning global kiwix stats for every source.

Progress column now shows "X / Y in Qdrant" when processing, or
"X / Y extracted" otherwise.
