feat(schema): Phase 1 schema templates + Nexus DevOps runbook

## AI Schema Assist Phase 1 (steps 1-2)

Approach A core (templates only, no LLM) — admin начинает создание нового
справочника с curated skeleton вместо пустого Monaco. Approach C (per-field
LLM suggest) — Phase 2 на этом фундаменте.

### Backend
- `templates/*.template.json` в ordinis-cuod-bundle resources — 6 шаблонов
  (blank/spacecraft/ground-station/antenna/frequency-band/operator)
- `SchemaTemplateRegistry` (rest-api) — classpath scan at startup, strip
  x-template-* metadata, expose canonical JSON Schema
- `SchemaTemplatesController` — GET /api/v1/dictionaries/templates (list)
  + /{id} (detail с schemaJson)
- Cross-bundle support: scanner matches classpath*:templates/*.template.json
  — другие bundles могут shippит свои templates через те же conventions

### Frontend
- types: SchemaTemplateSummary + SchemaTemplateDetail
- queries: schemaTemplatesQuery + lazy detail query
- TemplatePicker.tsx — grid of cards (icon + name + description + tags),
  click → fetch detail → fire onPick(detail)
- Integrated в DictionaryEditorDialog (create mode, properties.length===0
  visible — после первой property picker исчезает чтобы не перезатереть)

## Nexus DevOps handoff

`docs-internal/ops/nexus-alpine-mirror.md` — runbook про APKINDEX vs file
inventory drift на v3.23 mirror. Includes:
- Verification commands
- 3 fix options (invalidate cache / scheduled refresh / self-host)
- Prometheus alert proposal
- Current workaround (node:22-alpine3.20 pin) reference

Active issue paired с CI saga !227/!229/!230 — нужен DevOps action.
