feat(android): implement Phase 1 TimeSafari integration infrastructure

- Extend ConfigureOptions interface with activeDid integration options
- Add ActiveDid management methods to DailyNotificationPlugin interface
- Create DailyNotificationJWTManager for Android JWT authentication
- Extend DailyNotificationFetcher with Endorser.ch API support
- Enhance Android plugin with TimeSafari integration components
- Implement Phase 1 ActiveDid methods for web platform
- Update all test mocks to include new interface methods
- Add comprehensive error handling and logging

Phase 1 delivers:
✅ Extended TypeScript interfaces
✅ Android JWT authentication manager
✅ Enhanced Android fetcher with Endorser.ch APIs
✅ Integrated activeDid management methods
✅ Cross-platform interface compliance
✅ All tests passing

Ready for Phase 2: ActiveDid Integration & TimeSafari API Enhancement
