Refactor and clean up codebase

- Removed unused constants and type aliases in app_spi_command_defs.h and temp_sensor.h.
- Simplified ISpiCommandHandler destructor to default.
- Eliminated redundant methods and comments in temp_sensor and usart0 files.
- Consolidated writeU32Le function to app_spi_command_defs.h for reuse.
- Updated comments for clarity and accuracy in task_manager.h and task_runner.cpp.
- Removed hardfault.h as it contained no declarations.
- Cleaned up CANFD and watchdog implementations by removing dead code and unnecessary comments.
- Updated version numbers in config.h to reflect recent changes.
- Enhanced error handling and diagnostics in hardfault handling.
