translation and style fixes

(hasync) add dns resolver to sync, service restart not included, probably needs a seperate page at some point. closes https://github.com/opnsense/core/issues/923

o restructure session open/close for better visibility
o remove potentially insecure "try again" button
o remove override for switching csrf off (defer)

(dashboard, widget) spacing and small layout changes in ntp_status.widget.php, very anchient and unreadable code.... not spending more time on this now
