Summary:
Ref T4900. The root problem is that dragging stuff near the bottom of the board can cause jittery, jumpy behaviors.
Internal scrolling has changed the nature of this problem. Previously, the height of the board itself would jump around, but it's now fixed so the height of columns jumps around instead.
We could take the same approach and add a chunk to the bottom of each column when a drag starts, but this is really distracting visually since it's obvious to the user.
Instead, treat columns as infinitely tall (so dragging beneath them still counts as dragging to the bottom position).
Test Plan:
- View a board with a column taller than the screen (has a scrollbar).
- Drag a card to near the bottom position.
- Move the mouse down a little bit at a time, continuing toward the bottom of the page.
- Before patch: at some point, UI flips out and starts rapidly adding, scrolling, and removing the ghost.
- After patch: sensible behavior, ghost is in bottom position for all cursor locations.
Also works for dragging to the top.
(This leaves us with a little less dead space for cancelling drags, but you've still got the left menu, anything offscreen, and the escape key, which seems fine.)

Summary:
Ref T4900. This gets moves on the new stuff and cleans them up a little.
Two behaviors haven't been ported yet: height adjustment during drags (which is broken anyway with inner scroll) and updating point counts (coming soon).
Test Plan: Dragged cards around on a board, including top/bottom positions and normal/priority sort.

Summary:
Ref T4900. Broadly, workboard state management is fairly ad-hoc now, which makes things like this (where some kind of edit affects global state) difficult:
- Updating points header to reflect a sum change after dragging a task.
- Changing progress bars after editing a task to change resolution or points value.
- Moving a card to the correct column after editing it and changing subprojects/iterations.
- Responding to real-time notifications about other users moving cards.
This begins rewriting the code in a way that can better accommodate these kinds of far-reaching state update.
This change just moves cover image stuff. I'll continue moving features one at a time until boards work better.
Test Plan: Updated some cover images.
