Port satlover.de dual-station pass matching feature:
- New feature/mutual module with mutual pass data model
- MutualViewModel: compute overlapping passes for two stations
- ElevationCurveChart: Canvas-based dual elevation curve with drag
- MutualScreen: input form + results with expandable cards
- Navigation: add Mutual tab to bottom navigation bar
- i18n: add Chinese/English strings for new feature
Use MaterialTheme.colorScheme.primary for satellite name
text in all three lists (Components, SatellitesScreen,
PassesScreen), matching the color that was previously
used for the catalog number.
Remove the NORAD catalog number (e.g. '44444 - ') prefix
from satellite names in three places:
- Pass list items (Components.kt)
- Satellite selection list (SatellitesScreen.kt)
- Pass detail view (PassesScreen.kt)
The number is still accessible via satellite details if needed.
