Subject: [PATCH] Enhance FormBuilderComponents with Search and Filter
 Functionality

- Updated FormBuilderComponents.vue to introduce an enhanced search bar with filtering options for components, improving user experience in locating specific items.
- Added a filter dropdown to allow users to filter components by category, with clear options for selection and removal of filters.
- Implemented recently used components section to provide quick access to frequently utilized items, enhancing workflow efficiency.
- Enhanced search functionality to highlight matching components and provide feedback when no results are found, ensuring better usability.
- Updated styles for improved visual consistency and responsiveness across different screen sizes.
- Modified settings.local.json to include ESLint command in the allowed commands list for better development practices.
