[cli] Adds Actions to job status command output

[philrenaud]

Provides a little table showing Nomad Actions available to a job when running nomad job status $jobid. Mimics what we show in the Web UI (where there's an Actions dropdown on the main page of jobs that have 'em)

nomad job status actions-demo-service
ID            = actions-demo-service
Name          = actions-demo-service
Submit Date   = 2025-01-23T16:13:22-05:00
Type          = service

lgtm!

seems weird these may be empty. and could any of them be empty without all of them being empty?

[philrenaud]

You know, I think group/task can never be empty, and we explicitly guard against actionName being empty too. Maybe this is an unreachable condition?
