Minor, fix a Conduit issue with the bot?

Test Plan: do it live
This 'host' thing is not going to end well.
Don't validate Conduit hosts

Summary:
(See rPd1d3bf4e / rPf371c7b3.) Just get rid of this logic, I don't think there's any value to it.

IIRC, this was added a long time ago to deal with some issues that users had configuring things, but I think modern Phabricator covers all this stuff and I haven't seen any confusion from users for a year or more.

(Generally, I want to generally make Conduit easier to use, and this makes it more difficult.)

Test Plan: `grep`

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.

"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.
