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.
