Updated Feature: Enhancements to the Agreement Checker

The Agreement Checker is a helpful tool on the IREx homepage which helps see if potential sites have already executed reliance and broad indemnification emails for a selected sIRB. We have made enhancements to make this tool easier to use and more visually appealing. There is added informational text explaining that sites are only required to execute one reliance agreement offered on a study, even if they have executed multiple. The SMART 1, SMART 2, and Other Reliance columns have been shaded to show that all are considered a reliance agreement. The Other Reliance Agreement and Indemnification columns have been updated with an easy-to-spot ✔️check mark symbol. The csv export includes the full FWA number.
