make density-specific recovery assets

Provide different recovery UI resources for different display
densities.  Right now only the text images and the progress bars are
rescaled; the main icon will get scaled when it's updated for QP.

Lightly quantum-ify the rest of the recovery interface.  (Light
background, progress bars, etc.)
