Automatic Fan Curves Update (v7.0)

✨ Key Features Implemented:

1. Interactive Fan Curve Graph (.NET Canvas): Added a dynamic, clickable FanCurvePanel that allows users to seamlessly drag and drop temperature nodes to construct custom curves for both CPU and GPU.
2. Background Automation Daemon: Implemented a responsive multi-threaded FanCurveDaemon that quietly monitors temperatures in the background and applies interpolated fan speeds dynamically.
3. Smart Hysteresis & Default Safety Overrides: Safeguards fan operations with built-in hysteresis to prevent rev-jumping. Completely overrides to 100% maximum fan speed if the thermal envelope exceeds critical temperature targets.
4. Flexible Profile Management: Users can now create, name, edit, and persistently save multiple fan curve profiles.
5. Modernized Dark Aesthetics UI: Fully redesigned the entire Windows Forms interface incorporating a custom dark theme utility for a much sleeker experience.
