test(canvas): add form-inputs coverage (35 cases) + Section accessibility fix

+ form-inputs.test.tsx: 35 cases across TextInput, NumberInput, Toggle,
  TagList, and Section — pure presentational components in the Config tab.
  Uses vi.hoisted() patterns from established suite; no jest-dom matchers.

+ form-inputs.tsx (Section): add aria-expanded + aria-controls to the
  collapsible toggle button for WCAG 2.1 AA compliance. The content div
  gets a stable id derived from the title; aria-controls links button to
  region. Indicator span gains aria-hidden="true" (decorative only).
