Layer styling needs to be improved to see the results on analysis

[NyakudyaA]

Problem

the layer styling in the impact report makes it unusable - the style must be scale-appropriate and the impact layer must stand out over the exposure layer.

Solution

• @NyakudyaA to fix the style for layers
• The rendering order should have the generated impact layer as the top layer.
• The report should zoom to the extent of the hazard/exposure layer or the visible extent that was used in running the analysis

@gubuntu The style for the impact layers is generated from InaSAFE code. We would have to adjust that accordingly and come up with a suitable color range for the results. For now, I think they have generic styles for each combination of exposure/hazard.
@lucernae correct me if I am wrong
