On package installation dialogs, we should add "available storage" and "required storage" indications, same as Steam does. We then check the available size in the partition where dev_hdd0/game is located and required size for the package(s) and block the user from trying to install the package if the package is bigger than the available storage, as that will lead to a corrupted game install.

Examples from Steam:

• If the user does not have enough space, show a warning and do not allow the user to install the package until they free up enough space
  

• If the user has enough space, Install button becomes available
