Require "Can Edit" on a build plan to abort or pause associated builds

Summary: Fixes T9614. This is kind of silly, but stop users from fighting turf wars over build resources or showing up on an install and just aborting a bunch of builds for the heck of it.

Test Plan:
- Restarted / paused / aborted / etc builds.
- Tried to do the same for builds I didn't have edit permission on the build plan for, got errors.
