Covers add-time validation (unknown action, disallowed device,
out-of-range/wrong-type params, unknown kwarg - each rejected without
landing in the queue), the execution-time allow-list re-check as the
real safety boundary, the tomo_queue_actions global var matching the
live registry, tomo_queue_show()/the webpage generator surviving a
command job, legacy kind-less jobs still running as tomograms
alongside a real command-job device move, and the non-idempotent
resume prompt (distinct from the executor's own start-confirmation
prompt).
Also fixes flomni_sim: it only snapshotted/restored whatever was
already in the tomo_queue/tomo_progress global vars, so a stale entry
left behind by an earlier crashed run or manual debugging session
against the same shared sim Redis would contaminate every test that
assumed it started from an empty queue. Now resets both to empty at
setup, in addition to snapshotting/restoring around the test.
