fix(build): Refactor Vite config to correctly build editor styles.

This commit refactors the build process for the editor styles (style-editor.css) to use a dedicated Vite configuration instead of the problematic postcss-cli command.

Changes:

• A new vite.config.editor.js file is introduced to handle the editor-specific build.
• The build:editor script in package.json is updated to use Vite with the new configuration.
• The assets/css/styles.css entry point is updated to use the correct Tailwind v4 syntax that is compatible with the Vite build process.
• The generated style.css and style-editor.css files are now correctly ignored by Git.

This resolves the issue where the style-editor.css file was not being generated correctly, providing a more robust and maintainable build process.
