Split file loading into two separate buttons

- Add 'Load an Object' button for standard JSON files (.json)
- Add 'Load a Log File' button for JSON Lines files (.log)
- Each button has specific file type filter and handling logic
- Improved user experience with clear separation of functionality
- Add styling for the new info button (log files)
- Update documentation to reflect the two-button approach
