feat(phase2b): P2b.5 — Authority admin controls + new-stage panels (#182, v0.32.0)

Surfaces the master enable toggle (default OFF), per-category tier-map editor, citation threshold, and curate/seo/authority step panels + research-agent-count/editorial-max-rounds in Pipeline Settings. Image pipeline honors _prautoblogger_imagery_suppressed. Completes Phase 2b. QA APPROVE-WITH-P2 d1447340; CI green (phpcs+phpunit VPS-verified). 3 trivial P2 docs/cleanup follow-ups noted.
