Subject: [PATCH] varaverk: stretch CPU and GPU graphs to card bottom; add GPU
 history chart

- CPU/GPU cards: flex-column so body div takes remaining height
- CPU canvas: flex:1 + min-height:36px instead of fixed 36px
- GPU: add vvGpuHistory + canvas (purple, same style as CPU); canvas flex:1
  stretches to fill whatever space the row's tallest card leaves over
