✨ feat: enhance medialib image handling and add asset URL resolution

- Implemented `resolveApiAssetUrl` function to normalize asset URLs based on API base.
- Updated `MedialibImage` component to utilize new asset URL resolution and added support for alt text and class properties.
- Enhanced image loading behavior with improved width measurement and focal point handling.
- Added placeholder image handling and improved accessibility with alt text.
- Introduced new test script for auditing broken links in skill documentation.
- Expanded seeded test content to include medialib entries and updated related tests for pagebuilder previews.
- Improved global setup and teardown logging for clarity on seeded content management.
