Enhance UI components and styles for improved user experience

- Added global styles to hide scrollbars across all browsers for a cleaner interface.
- Refactored HistoryTable component to highlight currently playing audio with conditional styling.
- Implemented a confirmation dialog for deleting voice profiles in ProfileCard, enhancing user feedback and preventing accidental deletions.
- Updated ProfileList to rename the section from 'Voice Profiles' to 'Voicebox' for better branding and clarity.
