fix: prevent shop details page from failing when Qdrant API calls fail

Changed Promise.all() to Promise.allSettled() for Qdrant data loading,
allowing the shop details page to load successfully even if embeddings
or errors endpoints fail. The shop details API call is now prioritized
and Qdrant data is loaded as optional supplementary information.

This fixes the "Failed to load shop details" error when Qdrant endpoints
experience issues or are unavailable.
