[IMP] highlight: add drag & drop to array formula highlight

With this commit, it is now possible to drag & drop an array formula by clicking on its highlight.

[IMP] highlight: improve border hitbox

The hitbox for the borders of the highlight was not very well placed. There was some margins computations, I'm assuming they were there to avoid overlapping with the highlight corners but they we both wrong (there was overlap) and useless (the corner is above the border).

The highlight border was also not centered on the cell border, and was quite small, making it hard to click.

This commit removed the "margins", and widened and centered the borders.

[REF] highlight: rename Highlight component:

The component that handle highlight's UI interactions is named Highlight, which is the same as the type Highlight. This is annoying because we always end up importing the wrong Highlight, and need named imports if we want to use both the type and the component in a file.

This commit renames the component to HighlightOverlay
