Construction ghosts to show similar info to logistics requests

[mrbaggins]

If you're not aware, you can hover over logistics chests (providers and requesters) and be shown how many items are present, but also how many are currently on their way or about to be picked up.

Similarly in the player or chest logistics request screen, hovering over an item shows how many are on the way, available, etc.

What I am suggesting is that construction ghosts do something similar, where they show that a ghost has a reserved construction bot or not, and whether it's player or roboport based. Bonus points if it shows the "outside field of view" arrows that alerts do now to point where it's coming from.

Would also be useful to see how far away that bot is, given that a ghost is uniquely given a single bot, it's a single distance check, compared to logistics that likely have 10s or 100s for each item.

You already see the bot highlighted, which will place the entity.
