John Willard 8229972398 Tablet apps are now deleted when necessary & removes console preset. (#75863)
## About The Pull Request

Apps now properly delete themselves when removed, so they don't exist in
nullspace anymore.
Chat client now actually updates the uid, because its New() didn't call
parent.
Deletes the 'console' subtype of modular computer
Updates how downloading and transferring files are handled
Fixes being able to infinitely upload apps to a disk

## Why It's Good For The Game

Fixes some more bugs I found with apps and prevents spamming apps in a
disk.

## Changelog

🆑
fix: Maintenance data disks now properly transfer from PC to disk
fix: Disks can no longer be flooded with the same app repeatedly.
