[FEAT]: Export Model Config and Model at once, zipped

[dvince2]

Is your feature request related to a problem? Please describe.
Currently when a user exports a model config from the workflow node, what is exported is a configured AMR. If this is then imported back into terarium a default configuration is created for the mode with the correct values, however, its missing the "extra" information from that configuration like its name, description, sources etc

Describe the solution you'd like
Rather than exporting a configured AMR (or in addition to?), we want to export both the model's JSON and the configuration's JSON inside of a zip archive. This zip archive will then be able to be uploaded back into terarium to import both the model and the configuration with all of its information intact

Describe alternatives you've considered
Another option is using the AMR's metadata, but, this will result in a lot of edge cases to consider.
