treewide: rework uci change display

- Use native rpcd uci changes format instead of incompletely converting
   back and forth between the old and the new format
 - Rework uci changelog template to print the equivalent uci commands
   for the various changes
 - Rework theme headers to properly count the uncomitted changes
 - Rework theme CSS to properly style new changelog
