chore(release): bump version to v1.1.7

- workflow_registry.js: add force param to refreshRegistry(), bypass fingerprint
  dedup when responding to lora_registry_refresh WS message. Without this, the
  backend's wait_for_all() times out after 0.5s because the frontend skips the
  register-nodes POST when the workflow fingerprint hasn't changed (common after
  ComfyUI restart with an empty or unchanged workflow).
- misc_handlers.py: demote 'No nodes registered after refresh' from WARNING to
  DEBUG — empty workflows are a normal operational state, not a warning-worthy
  condition.
