fix: cli supports session-key & wallet options

[SgtPooki]

Needed on top of #103 in order to test session keys

Also:

1. cleans up some exit scenarios - exitCode = 1 instead of process.exit()
   • and cleanupSynapseService instead of cleanupProvider(provider)
2. auth input handling - shared cli auth helpers and types.. cleans up command code significantly.. shared auth options so names, descriptions, and defaults are normalized.

FYI I'm not against this, but I intentionally didn't add CLI args because there's complexity in dealing with session keys without offering utilities to make it easier to work with so I thought a hidden feature for now would be better. Funding and authorisation setup is the big problem, you've partly solved that with the new check-skip that you added but we're back at the problem of what happens if the wallet isn't properly set up, we have no catch for that.

I think we probably need to add back some checks and have proper early-fail conditions to make the UX more reasonable.

Also, I really like session keys for the github action, just like an API key. But we need better tools for it first so people can make them and manage them. @hugomrdias says he has ideas for a web UI for managing your session keys, if we get that then we should pivot the action to prefer them instead of your private key. Although we'd want to think about the auto-fund option since we don't (yet) have session keys doing payments stuff, but maybe we can do.
