Generate report output improvements

[TylerMuhly]

In the Summary report output:

• the radar plot circle values (-1, -0.5, 0, etc.) are not indicated as they are in the app
  • there is some overlap between the radar plot and heat map in the output
  • the heat map is cut-off of page (see example for: lakes_tsa, scenarios: lakes_northgrp_nh, lakes_northgrp_scen2, lakes_bau) when downloading pdf report
