feat: add cobra cli library

[oversize]

This PR adds cobra as the cli parsing library. #63

• I have copied the way cardano-up has used cobra more or less exactly
• The cli currently has the same ability as before. I wanted to start some better cli then "cli" but felt that it would be better to have some more discussion before implementing it. I will add my thoughts/ideas there
• I removed internal/logging in favour of internal/consolelog also stolen from cardano-up
• I needed to remove some loggig output from the api, because i dont know gin and did not spend time figuring out how to adapt slog to work with it. Also: I would like to suggest to remove gin and use go's 1.22 new stdlib net/http muxer instead. Removing the dependency alltogether. The api seems fairly simple so i think net/http is all we need. But i will open. another ticket for that discusson.

Looks like you have conflicts with main.

Oh snap, yes. I have merged these changes now and updated the commits.
I also just saw that cobra still provided its default "generate shell completion" script, which i now have disabled.

Back out the changes to remove the internal/logging module. I'm fine with the introduction of slog for console logging, but we need the access logs in the API to stay.

I have removed the console logging again in favor of internal/logging. I'll look into gin and how to have access logs with log/slog so we dont lose these when switching to it.
