Fix Ana Past 72-Hour Snow Water Equivalent Change

Past 72-Hour Snow Water Equivalent Change is not drawing. The service shows no error, but the symbology is not showing up in production.

It's difficult to identify what the original issue was. This service was accepted in a pull request from April 17th, 2023. In the original ticket 406 I mentioned that the files were pointing to local tifs. We used a different method for image layers a few years ago; we set symbology via mosaic datasets. So the service may have stopped working because it was not referencing the .mrf file. I corrected that in the mapx file and pushed the changes to an already existing dev-swe branch.

For my (and others) reference: In the HydroVIS google chat, it was mentioned that the Ana Past 72-Hour SWE Change mapx file was pointing toward 72_hour_accum_precip in several locations. I did some research and wanted to note that many mapx files point to 'incorrect' tables. Below Ana_past_14_day_inundation references srf inundation.xml files. And ana_snow_water_equivalent includes the past_72_hour_accum_precip schema in the mapx file several times, but neither of these services has drawing issues. I can't say what exactly is affected, but it could be the reference times of the data tables we attach in the mapx files. So we may be pulling reference times from incorrect services.

The drawing issues should be fixed with the attached pull request, however.
