- Fix compilation errors (missing imports for PropertyFactory and MaterialButton)
- Implement Pre-Trip Report with weather summary, boat profile, and sail suggestions
- Differentiate between active track (solid red) and past tracks (dotted red) on map
- Add navigation to Pre-Trip Report from Safety Dashboard
- Robustify track storage to preserve multiple tracks in session
