Hide fields

It should be possible to hide certain fields in the grid view.

A few things come to mind when working in this issue:

• The fields that are hidden must be stored in the backend.
• It should be possible to update the hidden fields via the existing view endpoint.
• The redoc API documentation must also be updated.
• The hidden fields and their values must still be available in the web-frontend even though it is hidden.
• The web-frontend should use v-if to hide the field and the cells to increase loading speed when scrolling through the rows.
• The hide fields context menu does not need to show a loading state.
• The hiding of fields can be instant, only when it is not able to save the hidden field in the backend the value should be reverted.
• What do we want to do with the primary field? Might be better to make it impossible to hide this field.
