Enhance App component with loading messages and UI improvements

- Added a loading message feature that cycles through various messages while the server is starting in Tauri.
- Improved the loading screen UI with a new layout and animations for the voicebox logo and loading text.
- Refactored the App component to include necessary imports and state management for loading messages.
- Updated styles for better visual appeal and user experience during the loading phase.
