With this PR, the appearance of trash can/delete icon is governed by the configuration variable, ENABLE_PATIENT_DELETE. Setting the variable to true will make the icon appear. The default value for the configuration variable is currentlyfalse - meaning that the trashcan icon won't be present by default. It means that we will need to set the variable to true for COSRI.. Or should the configuration variable has a true value by default so the trashcan icon is present by default?

I prefer a default of false for this, since the delete operation is rather undefined and dangerous (COSRI has a special carve-out since it can rely on the PDMP for re-population of most data).
