feat: add image input to art/avatar modes and notes to replace mode

- Art and Avatar modes now support optional image uploads via paste or
  file picker, sent to Gemini alongside the text prompt
- Initial Replace mode gains an optional textarea for notes to include
  with the uploaded image
- Backend updated to send user images for all modes, appending replace
  instructions only when in replace mode
- Send validation updated to allow image-only messages in art/avatar
