fix: remove --reward-cycle from stacks-signer run

[hstove]

Right now, when running stacks-signer run ..., you need to include a --reward-cycle argument. This is actually now longer used, but it's still required, so all of our docs/infra just use --reward-cycle 1.

This PR separates the args for run and dkg, so that you no longer need to pass --reward-cycle to run.

I've also added the short macro to all --config args, so you can optionally use -c.

NB: this will break existing infra as well as some of our docs, so we need to be mindful of updating them once this is merged.
