feat: register HttpAgent in CLI with --agent http --agent-endpoint (#119)

Adds `http` as a valid agent type across all three CLI subcommands
(mock, run, live). Requires `--agent-endpoint <URL>` when used.

Usage:
  openadapt-evals run --agent http --agent-endpoint http://gpu-box:8080
  openadapt-evals live --agent http --agent-endpoint http://gpu-box:8080
