Improvements to the ROI Calculator

This is an issue to help me keep track of the regressions that were reported to us via the slack channel #roi-calculator feel free to comment on anything new (or something that I might've missed)

Current Regressions

• Input fields not aligned on smaller screens
  • 
• Mobile version looks weird
• Colors of the table rows have a high contrast
• Specify the currency in the Average employee cost per hour to something maybe like Average employee cost per hour (USD) as to specify all of the prices are on U.S. Dollars
• Negative numbers are possible to add on the inputs

Will update the checklist as fixes are done and update this issue with the relevant MR(s)
