feat(approval): Approval Workflow v2 Phase 4 monitoring + pending-review badges

Approval Workflow v2 — Phase 4: monitoring + UX visibility.

Backend metrics (Micrometer → Prometheus):
- Gauge nsi_draft_pending_total — global queue depth (polled на scrape).
- Counter nsi_draft_submit_total{dictionary,operation,outcome=ok|already_pending|error}
  — submit attempts с разбивкой по outcome. Phase 3 lessons: error outcome
  выявит schema bugs которые ранее маскировались.
- Counter nsi_draft_decision_total{dictionary,operation,outcome=approved|rejected|withdrawn}
  — counts decisions, разбит по типу.
- Timer nsi_draft_review_duration_seconds — time-to-decide histogram (от
  submit до approve/reject/withdraw). publishPercentileHistogram() — для
  Prometheus histogram_quantile p95/p99.

DraftService:
- Optional<MeterRegistry> — null-safe в test ctor'ах.
- @PostConstruct registerGauges() — Gauge.builder polled от
  RecordDraftRepository.countPending().
- recordDecision() helper в approve/reject/withdraw — записывает Timer +
  Counter одной точкой.
- 4-arg ctor compat для Phase 1 unit tests.

UI (admin):
- useDictPendingDrafts — per-dict pending list, refetch 30s, gated на
  detailQuery.data.approvalRequired (no-op для не-approval dicts).
- "На review" badge в businessKey cell records table — моментальная
  видимость что есть pending draft. Open /reviews для act'а.
- i18n RU/EN: dict.pendingReview.label + tooltip.

Domain:
- RecordDraftRepository.countPending() — для Gauge polled count.

Tests: ordinis-rest-api unit 119/119, ordinis-app e2e 28/28, vitest 89/89.
