[IMP] portal: prevent duplicate views of portal wizard

The portal's granting access / revoking access / reinvite actions
return the wizard modal opening action in order to keep it open
and allow the user to keep browsing and managing portal access.

However, this can return the modal opening several times and execute
them all, generating several (unsynchronized) modal view instances
that the user sees and has to close one at a time.

Therefore the user field in the portal wizard receives a small widget,
that only allows one of these actions at a time. Clicking on other
buttons in the list while an action is ongoing will not do anything
since buttons are disabled for the time the action is being done.

Buttons showing the email_state will not do actions when clicked.

A short scss file is also added to the widget in order to make the elements
of the user_ids tree view as close to each other as possible. This prevents
in most cases the loss of buttons going off the list's width view and
generating a scroll bar, a situation to avoid since it does not show the
user the (dyamically appeared) action buttons. (e.g. when hiding buttons
if no valid email, then editing to a valid email, button reappearing out
of visible range)
