Student insertion from csv: fix issue with (**)

[giorio94]

Description

This PR fixes an issue concerning students' insertion from CSV, which occurs when the surname contains the (**) string (used by the portal to signal certain conditions). This includes the frontend, to appropriately remove it, and the backend, to prevent issues with names that end with a space (after the removal of invalid characters).
