feat: update BountyLive layout and user display

- Added an alias for the Admin module to streamline user management.
- Enhanced the layout of the main display area, adjusting padding and height for better usability.
- Updated the avatar fallback to show initials instead of the first character of the provider login.
- Refactored the exclusives assignment logic to utilize the Admin token for user retrieval, improving security and consistency.
