When a repository is inactive, mark its handle as "closed"

Summary: See downstream <https://phabricator.wikimedia.org/T182232>. We currently don't mark repository handles as closed.

Test Plan: Mentioned two repositories with `R1` (active) and `R2` (inactive). After patch, saw `R2` visually indicated as closed/inactive.
