Fix: Text import variant parsing now correctly handles value, price, and stock

- Fixed variant parsing to accept 3 fields: value, price override, stock quantity
- Removed invalid VariantTypes navigation property reference
- Auto-detect variant type (Weight for grams, Quantity for units)
- Format: - VariantValue; PriceOverride; StockQuantity
