feat(admin-ui): Phase 1 lineage UI — "Used by" + record refs cards

dict-relationships-v2 epic, Phase 1 admin UI. Backend endpoints поднимаются
коммитом 46a0a9c, тут — UI surface'ит их.

Что добавлено:
- `DictionaryDependentsPanel` — schema-level "На этот словарь ссылаются:"
  panel на странице справочника. Chip per (sourceDict.field → targetField,
  active records count, onClose mode badge: block/warn/cascade).
  Hide-on-empty: большинство справочников без incoming refs panel не видят.
- `RecordDependentsPanel` — record-level "На эту запись ссылаются:" section
  внутри `RecordHistoryDrawer`. Per-source summary chips + paginated items
  list (size=20, prev/next). Hide-on-empty.

Types в `client.ts`: `OnCloseAction`, `SchemaDependent`, `RecordDependent`,
`PerSourceSummary`, `RecordDependentsPage`.

Queries в `queries.ts`:
- `useDictionaryDependents(name)` — staleTime 5min (schemas slow-moving),
  404/403 → empty.
- `useRecordDependents(dict, key, page, size)` — disabled пока key undefined.

Mount points:
- `routes/dictionaries.$name.tsx`: `<DictionaryDependentsPanel>` после
  PageHeader, перед AOI banner.
- `components/record/RecordHistoryDrawer.tsx`: `<RecordDependentsPanel>`
  выше existing version timeline.

i18n RU/EN:
- `lineage.usedBy.{title,count,activeCount,openSourceDict}`
- `lineage.refs.{title,total,field,created,openSourceRecord}`
- `lineage.onClose.{BLOCK,WARN,CASCADE}` (показ как лейблы)
- `pagination.{prev,next,pageOf}` — общие keys.

Plurals: `_one/_few/_many/_other` для RU (правильная грамматика count'ов).

Verify:
- pnpm tsc --noEmit: clean.
- pnpm test (vitest): 89/89 PASS (4.04s).
- pnpm build: clean (warnings о chunk size — pre-existing для @nstart/ui).

Бекенд endpoints живут на:
- GET /api/v1/dictionaries/{name}/dependents
- GET /api/v1/records/{dict}/{key}/dependents?page&size
