EU legal guarantee notice and EU GARAN label

The notice images (images/notice) and the label templates (images/garan_template.png,
images/garan_nested_template.png) come from the files the European Commission publishes for
traders under Implementing Regulation (EU) 2025/1960:
https://commission.europa.eu/publications/practical-guidelines-and-high-resolution-vector-files-eu-notice-and-label-product-guarantees_en
(c) European Union, reused under the Creative Commons Attribution 4.0 licence
(https://creativecommons.org/licenses/by/4.0/), as the Commission's reuse policy provides
(Decision 2011/833/EU).

Changes: the notice images are the Commission's PNG files, renamed after their language code;
the English one, missing from the PNG set, was rendered from the Commission's SVG file at the
same size. The label templates are the Commission's SVG files without their three editable
texts (duration, brand, model identifier), rendered at three times their size; the plugin fills
those three texts in for each product, as the regulation allows.
