[FEATURE] Import accounts in console

[Rojoss]

Description

Currently it's only possible to export accounts. It would be useful to be able to import accounts again using the exported JSON file.

Ideally it would prompt to overwrite if an account with the same ID already exists. If the account doesn't exist it would create the account.

Ideally it would also import all other data from the account export such as storage objects. Alternatively it would be useful to be able to use an account export as input for the storage import to be able to import all storage objects that were associated with the user.
