Deterministic per-page storage keys mean a re-crawl overwrites the image but the
pages row survives the upsert, so analysis keyed to page_id (page_analysis/
search_doc, OCR, auto-tags, content-warnings) stayed stale forever and
force=false re-enqueue never re-analyzed it — poisoning search + the derived
manga_content_warnings (audit DB-1). persist_pages now detects conflict-updated
pages via xmax and clears their four derived tables in the same tx (the
content-warnings DELETE fires the mcw_* triggers), returning them to unanalyzed
so they re-derive. Tested.
