BatteryMeter: Isolate QS resources too, specify label as for status bar

- This way we can theme PA separately, will not reflect with CM
  so we don't end theming both CM statusbar and QS indicators while
  we want to do just QS and testing base is PA.

PS2: Use status bar color in style, is about the status bar icon so no need to keep using qs one.
PS3: Fix new array name
