Edit page: auto-expand step textareas, wider layout, image management

- Textareas auto-resize to fit content (min 120px)
- Edit page container widened to 1100px
- Show recipe image with URL input and file upload options
- Add image upload endpoint (POST /api/recipes/<backend>/<id>/image)
- Add upload_image_bytes() to both Mealie and Tandoor clients
