fix: Qdrant point ID format - generate valid UUIDs instead of invalid string IDs #75

- Add generatePointId() helper function to create deterministic UUIDs from platform/store/item IDs
- Fix WooCommerce sync: replace invalid string IDs with UUID format
- Fix Shopify sync: replace invalid string IDs with UUID format
- Resolves Qdrant API error: 'value is not a valid point ID, valid values are either an unsigned integer or a UUID'
- Products/orders/customers will now sync successfully to Qdrant vector database
