feat: Add services for managing trip-related data
- Implement EmergencyService for handling emergency contacts per trip. - Create GuestFlagService to manage guest mode flags for trips. - Introduce NotificationService with local notification capabilities. - Add OfflineFlagService for managing offline caching flags. - Develop PackingService for shared packing lists per trip. - Implement ReminderService for managing reminders/to-dos per trip. - Create SosService for dispatching SOS events to a backend. - Add StorageService with album image upload functionality. - Implement TransportService for managing transport segments per trip. - Create TripChecklistService for storing and retrieving trip checklists. - Add TripDocumentService for persisting trip documents metadata. test: Add unit tests for new services - Implement tests for AlbumService, BudgetService, EmergencyService, GuestFlagService, PackingService, ReminderService, SosService, TransportService, TripChecklistService, and TripDocumentService. - Ensure tests cover adding, loading, deleting, and handling corrupted payloads for each service.
