ci(ocr): reconcile caller to org standard (pinned)

Pin reusable workflow to a440b485d779b9177b1602c4d4f7f58cff0483a2 (main). Drop unknown with: inputs (llm_url/llm_model/use_anthropic not in workflow_call schema). Adopt pull_request_target + standard comment gates, guarded concurrency, minimal permissions, secrets: inherit.
