UX improvements to bad password in "Restore VMs from backup" tool

[bnvk]

Currently, when trying to perform a VM backup, and a user enters an incorrect password, they are given the following pop-up window:

Restore error!
Corrupted backup header (hmac verification failed). Is the password correct?

This text can be made more user friendly as Corrupted backup header (hmac verification failed). is highly confusing to non-crypto engineer users. I propose the following:

Error Restoring VM
The password you entered appears to be incorrect!

Additionally, if a user enters the incorrect password, the original backup window proceeds to the 2nd step VMs to restore except all the columns are blank (due to the password failing). The user must then click on the < Back button and manually delete, re-enter a second attempt for the password. This can be improved by simply staying on the original screen, and deleting the wrongly entered password from those input fields!

That error may also mean that backup is corrupted...
