feat(handoff): WorkflowBanner + table a11y + responsive + toast styling

Closing handoff gaps выявленных при полном audit'е README.md vs current
implementation. См. screen-by-screen mapping ниже.

== Screen 2 — Editor: WorkflowBanner (NEW) ==
Required by handoff (line 238-242) но не существовал. Inline status row выше
tab bar — live/review/info variants. Backend не имеет explicit dict-level
workflow state (draft → review → live transition), используем proxy:
  - approvalRequired=false      → 'Live' (green-bg + green left edge)
  - approvalRequired=true + 0   → 'Approval enabled' (accent-bg + accent edge)
  - approvalRequired=true + N   → 'На ревью N' (warn-bg + warn edge), link к /reviews

Backend extension future: добавить explicit workflowState к DictionaryDetail
+ buttons для transitions (request-review / approve / publish). Сейчас banner
дает минимум — visual workflow signal без UI mutation buttons.

== Table accessibility per handoff line 476 ==
TableHeaderCell:
  - scope='col' (a11y screen reader requirement)
  - aria-sort='ascending|descending|none' когда sortable prop true
  - New sortable + sortDirection props (API ready, не используется пока)

== 560px responsive per handoff line 466 ==
TableHeaderCell + TableCell получили optional hideBelow='sm|md|lg' prop:
  hideBelow='sm' → hidden <640px (table-cell ≥sm)
  hideBelow='md' → hidden <768px
  hideBelow='lg' → hidden <1024px

Callsites могут пометить secondary columns (created_by, updated_at, etc.)
hideBelow='md' для clean mobile experience. Текущие routes ещё не используют
prop — API ready для incremental adoption.

== Toast styling per handoff line 302-305 ==
Sonner toast — раньше surface bg + ink text. Handoff:
  - Navy bg + on-accent text (warm cream-orange feeling)
  - 4s auto-dismiss
  - Variant accent через left border 4px:
    success → green / error → pink / info → accent / warning → warn
  - cap-style title (но используем text-body для нативности, не overkill)
  - 13px font-sans

richColors disabled — наши tokens вместо sonner defaults.

Files:
  - NEW src/components/editor/WorkflowBanner.tsx
  - src/routes/dictionaries.$name.tsx (wire banner above tab bar)
  - src/ui/components/table.tsx (a11y + hideBelow API)
  - src/ui/components/toaster.tsx (navy variant + variant borders)
  - src/ui/index.ts (TableCellProps export)

Tests: 116 pass. TS strict clean.
