feat(admin-ui): visual schema builder для создания/редактирования справочников

Новый функционал — заводить свои справочники через UI без code deploy:

API:
- CreateDictionaryRequest type в client.ts
- useCreateDictionary / useUpdateDictionary mutations с invalidate
  ['dictionaries'] и ['dictionary', name]

Компоненты (src/components/schema/):
- types.ts: PropertyDef + buildSchemaJson() (Draft-07) + parseSchemaJson()
  для двусторонней конвертации между UI state и schema_json
- PropertyEditor: name + kind select + required + description + type-specific
  опции (minLength/maxLength/pattern для string; minimum/maximum для number;
  enum values; uniqueItems для array). Up/Down/Trash icon buttons
- SchemaBuilder: список property cards + кнопка «добавить» + EmptyState
- DictionaryEditorDialog: модалка с 3 табами:
  * Метаданные (name/displayName/description/scope/bundle/version/locales)
  * Поля (SchemaBuilder)
  * JSON (readonly preview сгенерированной schema_json)

Поддерживаемые типы полей: string, integer, number, boolean, enum,
localized (i18n object с patternProperties), date (format=date),
datetime (format=date-time), array_string (с опц. enum + uniqueItems).

Wiring:
- /dictionaries: PageHeader actions = «+ Создать справочник» → Dialog в режиме create
  → onSuccess navigate на /dictionaries/{name}
- /dictionaries/$name: PageHeader actions расширен «Схема» (secondary) +
  «Создать запись» (primary). Dialog в edit-режиме prefilled из
  detailQuery.data + parseSchemaJson()

i18n: 30+ новых ключей в schema.* / scope.* (RU/EN)
