mapSlurmStateToTaskStatus previously defaulted to 'running' for empty
state arrays and unrecognized states. This was too aggressive — treating
unknown as actively running could cause incorrect status updates when
Slurm returns unexpected or empty state data.
Now empty/unknown states return an empty string, and refreshTaskStatus
skips the update in that case.
RecoverStuckTasks now skips tasks that already have a slurm_job_id,
and ProcessTask adds a guard before the submitting step to prevent
re-submission even if a task is incorrectly re-enqueued.
Also deprecates POST /api/v1/jobs/submit endpoint (replaced by POST /tasks)
and comments out related handlers and tests.
Previously ValidateParams ran before WORK_DIR injection and file_ids mapping,
causing required parameter missing errors for auto-handled params. Now the
execution order is: inject WORK_DIR, map file_ids to file params, validate, resolve.

- ProcessTask injects $WORK_DIR only when script template uses it
- File/directory type params: resolves file_id to filename before rendering
- ValidateParams validates file/directory params as valid int64 file IDs
- RenderScript no longer shell-escapes file/directory type values
- Log rendered script before submitting to Slurm for debugging
