Enhance adjustment nodes with localized labels and improved state management

- Integrated localization for slider labels and prompts in color-adjust, curves, detail-adjust, and light-adjust nodes.
- Updated preset handling to include user-friendly prompts for saving presets.
- Improved state management for slider values and preset selections, enhancing user experience.
- Added reset actions to adjustment nodes for better control over user adjustments.
