Refactor SAR marker handling and add template management

- Updated CompassSarList and DetailedCompassDialog to use marker.displayName instead of marker.type.displayName.
- Enhanced DrawingLayer and DrawingMarkersLayer to support simple mode for drawing visibility and interaction.
- Added toggle switches in DrawingToolbar for showing/hiding received drawings and SAR markers.
- Modified MapMarkers to utilize custom emojis and display names for markers.
- Introduced RecipientSelectorSheet for selecting message recipients with search functionality.
- Refactored SarUpdateSheet to use SAR templates instead of marker types, allowing for emoji and name customization.
- Created SarTemplateEditDialog for adding and editing SAR templates with color selection and preview.
