Subject: [PATCH] Add SkywarnPlus-NG weather alerts integration

- Add SkywarnPlus config: master enable, API URL (CfgModel)
- Add showSkywarnAlerts() with severity-based color coding (viewUtils)
- Display alerts between node controls and favorites on main page
- When disabled: show nothing on main page
- When enabled, no alerts: simple one-line 'SkyWarn+NG: No Alerts' (no box/bold)
- Active alerts: severity colors (Extreme/Severe/Moderate/Minor)
- GitHub link on Cfgs page only
- Add SkywarnPlus config help in Cfgs tab
