feat(test-app): implement User Zero stars querying with 5-minute fetch timing

- Add comprehensive User Zero configuration based on TimeSafari crowd-master
- Implement stars querying API client with JWT authentication
- Create UserZeroView testing interface with mock mode toggle
- Add 5-minute fetch timing configuration for notification scheduling
- Include comprehensive documentation and TypeScript type safety
- Fix readonly array and property access issues
- Add proper ESLint suppressions for console statements

Files added:
- docs/user-zero-stars-implementation.md: Complete technical documentation
- src/config/test-user-zero.ts: User Zero configuration and API client
- src/views/UserZeroView.vue: Testing interface for stars querying

Files modified:
- capacitor.config.ts: Added TimeSafari integration configuration
- src/components/layout/AppHeader.vue: Added User Zero navigation tab
- src/router/index.ts: Added User Zero route
- src/lib/error-handling.ts: Updated type safety

Features:
- Stars querying with TimeSafari API integration
- JWT-based authentication matching crowd-master patterns
- Mock testing system for offline development
- 5-minute fetch timing before notification delivery
- Comprehensive testing interface with results display
- Type-safe implementation with proper error handling
