I would not expose all the argon stuff in the config.toml. We should either

• provide sub-command inx-chronicle jwt, or
• automatically generate the JWT in a dedicated output folder.

For both options, we should choose sensible defaults where possible.

I don't understand. This is fundamentally JWT configuration, so it should go there.
