account-settings: Pass password page params to dialog widget.

When the password change form was converted to a dialog widget
modal, in commit f5fbf5f, the page_params values for
password_min_length and password_min_guesses that were referenced
in the handlebars template `dialog_change_password.hbs` had no
value to set, which meant the password quality bar was no longer
checking the input value against those organization settings.

Passes the page_params values for password_min_length and
password_min_guesses to the html parameter in dialog_widet.launch
for the password change modal so that those values are available
and set when the template is rendered.
