Two related bug fixes:
- Transforms: `type: 'block'` callbacks must return a block instance created by createBlock; the previous code returned raw attribute objects which WordPress silently ignored, so the toolbar block-switcher transforms never fired. Update tests to assert on `result.name` and `result.attributes`. Add a manual jest mock for @wordpress/blocks since the package is provided at runtime via dependency-extraction-webpack-plugin.
- Filter CSS: the SCSS used a descendant combinator (`.wp-block-ksolo-image-filter .has-filter-warm img`) but the JSX puts both classes on the same element, so the filter rule never matched and picking a filter had no visual effect on the editor or the front end. Target the inner <img> by its stable class pair (`.ksolo-image-filter-img.has-filter-<slug>`) instead. Add a regression test that reads the compiled CSS and asserts the selectors are present for every preset.
