docs: wiki staleness sweep (Fable-orchestrated Opus audit)

Audited all 40 docs/ against the live codebase; fixed factual staleness in 23,
14 were clean. Highlights (all verified against code):
- equipment -> machines (ADR-011 rename) in INSTALL/DEPLOY-WINDOWS-IIS,
  PLUGIN-GUIDE, GE-ENFORCE, ROADMAP.
- Versions refreshed: contract 0.10.0 -> 0.13.0, product 0.5.0 -> 0.7.0, plus
  plugin example core_version pins.
- Bundled set corrected to the current 13 (PLUGINS.md 7 -> 13 rows; DEPLOY
  eleven -> thirteen).
- Per-plugin Alembic chain workflow (ADR-008) replacing stale core-chain steps
  in PLUGIN-QUICKSTART / BACKUP-RESTORE; deploy adds plugin upgrade-all.
- Frontend plugin staging (ADR-010) replacing 'no frontend plugin system yet'
  in PLUGIN-GUIDE; view/route paths repointed to plugins/<name>/frontend/.
- Corrected file paths (MapView.vue, manifest_schema.json), CLI (shelf-list),
  API gating (GET /api/plugins is optional-jwt), WJF 15 -> 16 stages, and
  retired Collector/PC-Types settings pages (ADR-012).
- ge-enforce proposal marked ACCEPTED/built.
