refactor(ui): Optimize mouse area generation for volume and node widgets

- Improve code formatting and readability in node_widget.rs
- Reduce code complexity by breaking long lines and improving indentation
- Optimize mouse area generation with more precise segment calculations
- Add more consistent spacing and alignment in volume and node widget implementations
- Minimize code duplication in mouse area generation methods
