Add migration for DiscountProductImages table

- Created a new table `DiscountProductImages` in the CMS schema.
- Added columns for image details including `Title`, `AltText`, `ImagePath`, `ThumbnailPath`, `SortOrder`, `IsActive`, `Created`, `CreatedBy`, `LastModified`, `LastModifiedBy`, and `IsDeleted`.
- Established a foreign key relationship with the `DiscountProducts` table.
- Created indexes on `DiscountProductId` and a composite index on `DiscountProductId` and `SortOrder`.
