Summary

wp-curate issue #51: Add support for selecting a layout

This PR introduces comprehensive support for selecting layouts and block patterns in the wp-curate/query block, aligning it with the functionality found in the Columns and Query Loop blocks. The implementation includes both JavaScript/React and PHP enhancements to enable variation and pattern selection, as well as improved extensibility for future layouts.

Notes for reviewers

• The block now supports a layout property, enabling users to choose among different layout options (with "list" as the default).
• Pattern and variation selection modals have been integrated, allowing users to initialize blocks with custom content or layouts.
• Block variations and block patterns are now registered via both JavaScript (block.json, registerBlockVariation()) and new PHP classes.
• Utility functions and TypeScript types have been introduced to support pattern searching, selection, and transformation.
• The main plugin initialization now includes new features for block variations and block patterns.
• The PR includes dependency upgrades and some minor code cleanup and refactoring.

These are proof of concept patterns. The real patterns will be better named, be more different, etc.
