Refactor UI imports and clean up unused code

- Removed unnecessary imports from various UI files to streamline the codebase.
- Deleted the unused documentation viewer implementation in `documentationview.py`.
- Cleaned up imports in `files.py` by removing `LOG_DIR` as it was not used.
- Removed the temporary script `temp.py` as it was no longer needed.
