FX-3: project image-only papers to Neo4j after auto-map

Only the born-digital fast path enqueued project_template_safe; the async OCR
job (_run_auto_map_job) — where image-only papers, R3's primary target, are
routed — never projected, so those papers never reached the graph after
auto-map. Project at the end of the async job too.

Adds test_auto_map_ocr_path_projects_to_neo4j.
