Dries Peeters 9d1ece5263 feat: Implement comprehensive architectural improvements and new features

This commit implements a complete architectural transformation of the TimeTracker
application, introducing modern design patterns and comprehensive feature set.

## Architecture Improvements

### Service Layer (18 Services)
- TimeTrackingService: Time entry management with timer functionality
- ProjectService: Project operations and lifecycle management
- InvoiceService: Invoice creation, management, and status tracking
- TaskService: Task management and workflow
- ExpenseService: Expense tracking and categorization
- ClientService: Client relationship management
- PaymentService: Payment processing and invoice reconciliation
- CommentService: Comment system for projects, tasks, and quotes
- UserService: User management and role operations
- NotificationService: Notification delivery system
- ReportingService: Report generation and analytics
- AnalyticsService: Event tracking and analytics
- ExportService: CSV export functionality
- ImportService: CSV import with validation
- EmailService: Email operations and invoice delivery
- PermissionService: Role-based permission management
- BackupService: Database backup operations
- HealthService: System health checks and monitoring

### Repository Layer (9 Repositories)
- BaseRepository: Generic CRUD operations
- TimeEntryRepository: Time entry data access
- ProjectRepository: Project data access with filtering
- InvoiceRepository: Invoice queries and status management
- TaskRepository: Task data access
- ExpenseRepository: Expense data access
- ClientRepository: Client data access
- UserRepository: User data access
- PaymentRepository: Payment data access
- CommentRepository: Comment data access

### Schema Layer (9 Schemas)
- Marshmallow schemas for validation and serialization
- Create, update, and full schemas for all entities
- Input validation and data transformation

### Utility Modules (15 Utilities)
- api_responses: Standardized API response helpers
- validation: Input validation utilities
- query_optimization: N+1 query prevention and eager loading
- error_handlers: Centralized error handling
- cache: Caching foundation (Redis-ready)
- transactions: Transaction management decorators
- event_bus: Domain event system
- performance: Performance monitoring decorators
- logger: Enhanced structured logging
- pagination: Pagination utilities
- file_upload: Secure file upload handling
- search: Full-text search utilities
- rate_limiting: Rate limiting helpers
- config_manager: Configuration management
- datetime_utils: Enhanced date/time utilities

## Database Improvements
- Performance indexes migration (15+ indexes)
- Query optimization utilities
- N+1 query prevention patterns

## Testing Infrastructure
- Comprehensive test fixtures (conftest.py)
- Service layer unit tests
- Repository layer unit tests
- Integration test examples

## CI/CD Pipeline
- GitHub Actions workflow
- Automated linting (Black, Flake8, Pylint)
- Security scanning (Bandit, Safety, Semgrep)
- Automated testing with coverage
- Docker image builds

## Documentation
- Architecture migration guide
- Quick start guide
- API enhancements documentation
- Implementation summaries
- Refactored route examples

## Key Benefits
- Separation of concerns: Business logic decoupled from routes
- Testability: Services and repositories can be tested in isolation
- Maintainability: Consistent patterns across codebase
- Performance: Database indexes and query optimization
- Security: Input validation and security scanning
- Scalability: Event-driven architecture and health checks

## Statistics
- 70+ new files created
- 8,000+ lines of code
- 18 services, 9 repositories, 9 schemas
- 15 utility modules
- 5 test files with examples

This transformation establishes a solid foundation for future development
and follows industry best practices for maintainable, scalable applications.
