refactor(repository): replace queryFactory with DbSetFactory in DbRepository

- Updated DbRepository constructor to use DbSetFactory<TDbContext, TEntity>
  instead of a Func<TDbContext, DbSet<TEntity>> queryFactory.
- Adjusted namespace imports to include DigitalData.Core.Infrastructure.Factory.
- Improved repository instantiation consistency and encapsulation.
