KRACOEUS-8197 Changed visibility of copy link

according to https://docs.google.com/a/kuali.org/spreadsheets/d/1v3eVAh06KM5mX81VYRpYoRKUgrTcX20ukYG4NwQbfU8/edit#gid=1247911931

Copy should be conditionally displayed based on either a person has create proposal development document permission which what controls full entry.  Is there a change in requirements?  Maybe we need a new edit mode for "copy" that isn't tied to the edit mode full entry which also considers document locking?
