QueuePanel reused one pixel TransformState for all non-fine-tuned items,
mis-placing garments/prints of other sizes. Store the ratio-based template
instead and recompute each item from its own garment/print size.
- add core.composer.image_size() and resolve_transform() (pure, tested)
- queue: set_template() replaces set_transform(); per-item resolve + size cache
- template_panel: expose current_template(); main_window pushes it to the queue
- tests: +4 covering fine-tune precedence, per-size recompute, empty inputs
