feat: enhance media asset lifecycle management and permissions

- Introduced new API endpoints for bulk lifecycle actions and bulk patching of media assets, allowing for more efficient management of multiple assets.
- Updated media lifecycle permissions to restrict actions based on user roles, ensuring that only superadmins can perform critical operations like purging and force lifecycle changes.
- Enhanced frontend components to support new bulk actions and improved user experience in the media library, including visibility and copyright management.
- Incremented version to 0.8.49, reflecting the latest improvements in media handling and governance.
