Creating accounts with very long emails results in a 500 server error

[stefanotroncaro]

Using the create user endpoint with very long emails bypasses pydantic validation, and raises an IntegrityError when sqlalchemy makes an insert statement.

Example email:

• abcdefghijabcdefghijabcdefghijabcdefghijabcdefghijabcdefghijabcd@abcdefghijabcdefghijabcdefghijabcdefghij.com
