feat(M3): dossier edit+rerun UI, F2/F3, run-list badges — v0.20.0

- Dossier_Actions (4 AJAX endpoints, manage_options+nonce): save fork /
  queue replay / queue rebuild / stage-status poll. Run identity always
  derived server-side from post meta; the AJAX layer validates + queues
  ONLY — all mutations happen in the cron handlers (chained-cron, CPO
  hard constraint). Fork saves lock message structure (count/roles) so
  every version stays replayable.
- Edit panel per editable stage: per-message textareas prefilled from
  the latest fork or the recorded request_json; explicit fork +
  downstream-stale + queued-execution copy; spend strip with ceiling
  warning (filterable fraction, default 0.8). Disabled stages always
  show WHY (policy reasons; missing-input retention copy).
- Stale / human-edited / attempt chips per stage + header badges (M2
  slot filled); dossier polls stage status while a re-run is active
  (board poll interval setting) and re-renders when the run settles.
- F2: sidebar Models & Prompts card (per-stage model/pv/role) + Run
  Spend card. F3: log-only stages (image_a/b, llm_research, ...) render
  from generation_log + the _prautoblogger_image_role attachment grid.
- M2 correctness: dossier is now item-scoped (idea-hash meta) and
  excludes gen_log rows linked to other posts of a multi-article run.
- Run-list visibility (product AC): board cards get a Human-modified
  chip; Review Queue rows get a stale-stages chip linking to the
  dossier. Both via single batched queries (no N+1).
- v0.20.0 + CHANGELOG + ARCHITECTURE #24 (+ file tree, schema tables,
  db-version note) in this commit per versioning discipline.
