When moving an object between workboard columns, require object edit permission

Summary:
Fixes T5204. Currently, to move an object (like a task) between columns on a workboard, you must be able to edit the project.

This doesn't map very well to real usage. Instead, require users be able to edit the object (e.g., the task).

(You still need to be able to edit the project to create columns, edit columns, etc.)

Test Plan: Moved stuff around on a project I could not edit.

Always show repository in Differential emails.

Test Plan: Not tested.

"Hide" columns instead of "Deleting" them

Summary:
Fixes T5342. Fixes T5161. Previously, we were a bit strict about deleting columns because you could orphan tasks. Let users recover these columns more easily so they can't shoot themselves in the foot.

  - Change "Delete" language to "Hide".
  - Add a button to let you see hidden columns.
  - Remove restriction that you can only delete empty columns.

The new button is a little funky, but maybe it merges into the "Add Column" button and that becomes a dropdown with board actions? The rest of this feels OK to me.

Test Plan: See screenshot.

Allow the Default/Backlog column to be renamed

Summary: Fixes T5101. There's no technical reason not to allow this, it just took a little extra work so I didn't do it originally.

Test Plan: Renamed "Backlog", un-renamed it. Tried to hide it.
