VERSION: bump to 3.0.1

# Version 3.0.1 🚀

### CoolerControl 4.0 Support

This release adds full compatibility with CoolerControl 4.0, which introduces significant security and authentication changes. Please read the following carefully before updating.

---

### ⚠️ Action Required — Auth Token Setup

CoolerControl 4.0 now requires authentication for API access. To continue using CoolerDash with CC4, you need to create an **Access Token** in the CoolerControl UI:

1. Open the CoolerControl UI
2. Navigate to left down corner press the 🔒**→ Access Token**
3. Generate a new Access Token
4. Copy your token-key `cc_ `
5. Enter the token in CoolerDash's connection settings in the Plugin-UI

---

### Changes

- **feat:** CoolerControl 4.0 support — TLS verification, token-based auth, LCD upload, native shutdown image
- **feat:** New configuration fields for CC4 connection settings
- **ui:** Moved expert settings to a dedicated tab
- **fix:** Stale INI/filename references resolved
- **plugin:** Removed deprecated services and functions
- **docs:** Updated guides and documentation for CC4
