Change label to "Reset Password" and get button out of tab ordering

In a keyboard-intensive patron input workflow, pressing tab should
not place focus on the "Reset Password" button; the password is
automatically generated at dialog creation time. Setting tabIndex
to -1 disables tab focus for the button.

Also, the button has been relabeled to "Reset Password" to be
consistent with the previous button.
