fix(admin-ui): DatePicker + nested object + raw record fetch для Edit

Несколько связанных багов в форме записей:

DatePicker:
- launch_date / decay_date (format=date) и validFrom/validTo рендерились как
  raw text input → теперь @nstart/ui DatePicker с RU локалью.
- DatePickerProvider добавлен в main.tsx с DATE_PICKER_LOCALE_RU.
- Far-future infinity dates (year>=9999) скрываются (пустое поле).
- ISO date format на submit: yyyy-MM-dd.

Nested object → JsonField fallback:
- orbit (type=object с raan_deg/eccentricity/...) и antennas (array of object)
  показывали [object Object] в text input. Добавлен JsonField — TextArea
  с JSON.stringify/parse, локальный state для невалидного промежуточного
  ввода + inline parse error.

Edit raw record fetch:
- Read-api flatten'ит i18n в строку выбранной локали → form для edit получал
  data.name = 'Terra' вместо {ru-RU, en-US}. На Edit теперь fetch raw record
  через writer GET /api/v1/dictionaries/{name}/records/{businessKey}.
- nginx regex location ~ ^/api/v1/dictionaries/ → writer (вместо узкого regex
  только для /dictionaries/{name}). GET schema, GET raw record, mutations —
  всё на writer. Read-api держит /api/v1/{name}/records/* (другой URL pattern).
- LoadingBlock пока тащим raw запись + Alert на ошибке.
