feat(drawer): all-sections layout с chips strip per handoff prototype

Handoff Screen 3 RecordDrawer показывает sections подряд с chips strip
для quick jump, не tabs (currently SchemaDrivenForm has 3 tabs).

SchemaDrivenForm:
  - New optional prop layout: 'tabs' (default, legacy) | 'sections'
  - В sections mode:
    * Section chips strip на верху (sticky top-0) вместо Tabs
    * Chip = bucket name + field count в Mono
    * Click chip → scrollIntoView к section
    * Все 3 buckets рендерятся подряд (visible одновременно)
    * Каждая section получает sticky h3 cap header + scroll-mt-12
    * z-indexed sticky: chips strip = 10, section headers = 5
  - В tabs mode: backward-compat без изменений

RecordDrawer callsite (dictionaries.$name.tsx):
  - Передаёт layout='sections' в SchemaDrivenForm (create + edit)
  - Существующий tabs API остаётся для test'ов которые используют default

Layout matches handoff Screen 3 prototype:
  [chips strip sticky]
  [section: Основное]
   field grid 2-col
  [section: Описание (i18n)]
   localized fields
  [section: Дополнительно]
   optional fields grid

Future Phase B refactor: backend x-section schema metadata (open question
#5) разблокирует per-property sections (вместо bucketing). Текущий
fallback bucketing (identity/description/extra) достаточен для MVP.

Tests: 116 pass (test использует default 'tabs' layout, не разломан).
