Comment 1 for bug 1861331

I just ran into this on a project! Here's a branch that adds [flairColumnHeader] as an input on eg-grid and changes the Sandbox flair column title to "Status" by way of example: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sleary/LP1861331-configurable-flair-column-header-title

To test, visit /staff/sandbox and scroll down to the first grid. Hover over the bell icon; you should see that the tooltip is now "Status" instead of "Notifications."
