fix(demos/manymove_industrial): declare conveyor-line component + relax smoke poll filters

The container_scripts/conveyor-line/ directory expects a manifest
component with id 'conveyor-line' (mirroring the manymove-planning
pattern earlier). Without it, gateway returned 404 on
inject-photoeye-flicker / restore-line script executions.

Also relax smoke test status filters: MANYMOVE_SELFTEST is severity 0
INFO so may not pass debounce to CONFIRMED in time; just check the
fault appears in /faults at all. For PLC heal, accept PREPASSED in
addition to HEALED since the healing threshold may not be crossed
within the 30s window from a single PASSED event.
