feat(editor): left info panel + 3-col layout per handoff prototype

Handoff prototype design/compact.html показывает editor как 3-col layout:
[Sidebar 220 (global nav)] [InfoPanel 220 (dict metadata)] [main content].
Текущая implementation была 2-col (nav + everything).

NEW src/components/editor/EditorInfoPanel.tsx:
  - Scope badge (PUBLIC/INTERNAL/RESTRICTED) — top
  - ОПИСАНИЕ section — caption + dict.description body
  - Metadata 2x2 grid: Bundle / Версия / Записей / Локали
    (mono text-ink-2, cap labels)
  - СВЯЗИ section с двумя группами:
    → ссылается  outgoing FK list (name links к /dictionaries/$name)
    ← используют incoming refBy list (deduplicated sourceDict names)
  - sticky lg:top-2 self-start чтобы panel оставалась видна при scroll
  - lg:max-h-[calc(100vh-7rem)] overflow-y-auto если metadata высокий

src/routes/dictionaries.$name.tsx:
  - Обернул содержимое (banner + tabs + tab content) в:
    <div className='grid grid-cols-1 lg:grid-cols-[220px_1fr] gap-4 lg:gap-6'>
      <EditorInfoPanel ... />
      <div>{banner + tabs + content}</div>
    </div>
  - На <lg переключается в stacked (info above content) — single column
    благодаря grid-cols-1.

PageHeader остаётся выше grid (full-width breadcrumb + title + actions).
Action buttons (AOI / Time-travel / Schema edit / Создать) живут в
PageHeader.actions slot — handoff prototype показывает их в info panel,
но рядом с title лучше discoverable. Может уйти в info panel в future
refactor.

Tests: 116 pass. TS strict clean.
