Print the error detail from the cli

[d-perl]

When a user does blueapi controller run <...>, getting a message which simply says "Error 422" is not very helpful. The server does define error response detail, this should be printed in the console.

@stan-dot has previously expressed a preference for terse output, maybe we should just add a --verbose flag and let the user decide?

I believe this is the connected issue

#206

where in the comment thread we've got this

#206 (comment)

and the PR has this:

fwiw we could add formatting like in here: https://github.com/DiamondLightSource/blueapi/pull/527/files

Sure, I'm ok if it's behind a flag, I just don't want to have to run the server in a debugger just to find out how my params are wrong

I looked into using built-in fastapi functionality to provide clearer error messages from the server but ran into an upstream issue, discussion here: fastapi/fastapi#13278 (reply in thread)
