refactor: fix embeddings endpoint to return actual embedding records

Previously the /embeddings endpoint was returning shop_content records
with fake embedding data, causing confusion about pending/completed status.

Changes:
- Added getAllShopEmbeddings() to get actual embeddings from shop_embeddings table
- Fixed getShopQdrantEmbeddings endpoint to return real embedding records
- Added 'pending' count to getShopEmbeddingsStats for better visibility
- Now returns accurate embedding_status from the actual embeddings table

This fixes the misleading '27 pending' display and makes the API consistent
with the actual database state.
