fix(radix): map Waiting/Active to STARTING; add Stopping/DeadlineExceeded

Radix's batch-job scheduler reports Waiting (image pull, pod
scheduling) and Active (job resource created, pod not yet Running)
before Running. Both were falling through to JobStatus.UNKNOWN,
which is what users see for the first ~30-60s of a new job.

- Waiting, Active         -> STARTING
- Stopping, Stopped       -> FAILED ('Radix job was stopped')
- DeadlineExceeded        -> FAILED ('exceeded active deadline')
- default arm now logs a warning with the unmapped status string
  and echoes it back in the message, so future gaps surface with
  the actual value instead of a generic 'unknown status code'.
