SQLMesh UI doesn't use dialect when displaying the model column data type

[codykonior]

When running sqlmesh ui and accessing a model like http://127.0.0.1:8000/data-catalog/models/some_model_name it's giving column types like VARCHAR and hiding all of the underlying type data like that it's actually NVARCHAR(MAX). This is because it's using str(data_type) instead of using the model dialect via data_type.sql(dialect=model.dialect).

You can fix this in web\server\api\endpoints\models.py by changing:

        columns.append(models.Column(name=name, type=str(data_type), description=description))

To:

        columns.append(models.Column(name=name, type=data_type.sql(dialect=model.dialect), description=description))

Which works on my machine. This isn't critical because I will switch to using Python instead of the API but it might be nice for others!
