fix: import DB errors

[betodealmeida]

SUMMARY

When importing a dashboard that has a database with a masked password we ask for the password even though later we reject the import because the type is wrong.

This PR improves the logic of hasTerminalValidation, a helper function that determines if we should prompt for password and/or overwrite, or if we should show an error message on a failed import.
