feat: Add image generation for SVG logos and improve clipboard functionality

- Added @resvg/resvg-js dependency for SVG to PNG/JPG conversion.
- Implemented pregeneration of PNG and JPG images from SVG files in the scanLogos script.
- Enhanced copy URL functionality in App.svelte to support modern clipboard API with fallbacks.
- Removed unnecessary onCopy prop from LogoActions component and handled copy actions locally.
- Introduced notification system for copy actions with success/error feedback.
- Updated styles for action buttons and notifications for better user experience.
- Cleaned up unused code and improved overall structure for clarity.
