fix: textarea height setting now visibly changes empty-state size

Browse Source 
The previous approach used a 600ms preview animation + syncHeight() which
collapsed the textarea back to 1 line (empty scrollHeight). Now syncHeight
enforces minHeight = maxHeight/3, so each setting (S/M/L) has a visibly
distinct resting height even when the input is empty.

  S (120px): min ~40px  ≈ 1-2 lines at rest
  M (240px): min ~80px  ≈ 3 lines at rest
  L (480px): min ~160px ≈ 5-6 lines at rest
