When importing data from a CSV file, there is a step to review the first 50 lines of the data file prior to uploading the full file. Is there a facility to review the “raw” data AFTER importing and without creating a new insight?

The whole input data goes through a validation against the model, so only input data in the expected format are loaded otherwise the data load fails. So there is no need to validate data after import of CSV. The preview is there just for the first time when you also create dataset for your model based on the CSV file. The preview allows you to choose right type of fields for the dataset based on data in the CSV. There you choose if the dataset field will be attribute or fact or something else based on the first couple of lines you see in the preview.
There are couple of advanced situation for which a validation would be useful and it is e.g. check of referential integrity between dataset. We have a functionality for that. It can do multiple validation checks of the project. The functionality is described in the following article: https://help.gooddata.com/doc/free/en/workspace-and-user-administration/administrating-workspaces-and-workspace-objects/validate-a-workspace
