Add autocompletion for password reset

Using autocomplete="current-password" and autocomplete="new-password"
will help browser with integrated password managers to generate safe
password for the users.

See https://developer.apple.com/documentation/security/password_autofill/enabling_password_autofill_on_an_html_input_element
and https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input/password#allowing_autocomplete

.

Also unify autocapitalize="none" autocorrect="off" behavior in a few
other places for password input fields.
