A disabled device with historical readings still cannot be deleted by default
(409 guard stays, to prevent accidental data loss). A new explicit opt-in lets
the user remove it for real:
- DELETE /api/modbus/devices/{uuid}?cascade=true removes the device's readings
and exposed_entity_toggle rows, then the device, in one transaction (FK order:
readings before device). Best-effort clears the HA discovery configs first
(MQTT not connected -> no-op, never blocks the delete). Default (no cascade)
unchanged. Returns 200 with deletion counts.
- Frontend: a 'Force Delete (all data)' button appears only after the 409, with
a red irreversible warning; cascade is sent only on that explicit action.
- Also corrected a stale comment: FK RESTRICT IS enforced at runtime now.
