Fixed two critical issues preventing forecast data from being cloned:
1. **Missing batch_name field**: The fixture uses `batch_id` but the
PredictionBatch model requires `batch_name` (NOT NULL constraint).
Added field mapping to handle batch_id -> batch_name conversion.
2. **UUID type mismatch**: The fixture's `product_id` is a string but
the Forecast model expects `inventory_product_id` as UUID type.
Added conversion from string to UUID.
3. **Field mappings added**:
- batch_id -> batch_name
- total_forecasts -> total_products
- created_at -> requested_at (fallback)
- Calculated completed_products from status
These fixes enable the forecasting service to successfully clone all
28 forecasts from the fixture file, unlocking demand forecasting
AI insights in demo sessions.
