GOOD Refactor GUI components and add PlainSlider widget

- Added a new `PlainSlider` widget for keyboard-editable numeric sliders.
- Updated various panels to utilize the new `PlainSlider` for better user interaction.
- Removed unused code and dead code warnings across multiple files.
- Improved organization of modules by adding a `widgets` module.
- Cleaned up imports in several files to streamline the codebase.
- Added Qodana configuration file for code analysis and quality checks.
