[$25] Disable Job Edit form when status is "assigned", "cancelled" or "closed"

[maxceem]

If job status is "assigned", "cancelled" or "closed" we should disable on the field in the Job Edit form except of "status" (so we should be able to edit status).

Example job: https://platform.topcoder-dev.com/taas/myteams/16873/positions/edda7f39-5297-461a-89be-2074faa8bdc8/edit
