    status/payg: add menu action to apply a code before PayGo time is expired
    
    With this change, the PAYG status applet supports entering a credit
    code before credit has expired. Without this last feature, users are
    forced to deal with the "credit expired" screen on its timeline rather
    than theirs (and without the implication that they're falling behind on
    payments).
