Subject: luci-app-nlbwmon: improve initial view

Make sure that placeholder pie charts are rendered, display a hint about
yet missing data in the tables and offer a link to force-commit ("Reload")
the data.

Also fix some mixed white space, an imbalanced dom operation and sync
translation template.
