Jordan Dominion 37df0a0cbe Lootpanel Improvements (#94995)
## About The Pull Request

Makes the lootpanel act like you'd expect it to.

## Why It's Good For The Game

You should not need to manually refresh the loot panel. You should not
be able to monitor a turf on the other side of the station.

## Changelog

🆑
fix: The lootpanel will now properly close with distance from the target
like most other tguis.
qol: The lootpanel will now automatically refresh when new items enter
it. Removed the manual refresh button.
