Modernize Todo App: Enhanced Data Model and Architectural Improvements

Description

Summary of Work

This pull request represents a significant refactoring of the Todo application's core data infrastructure, focusing on improving code quality, type safety, and maintainability.

Key Objectives:

• Standardize the data model across the application
• Introduce robust validation and type handling
• Consolidate duplicate entities and improve code organization
• Enhance test coverage and reliability

The changes address technical debt and prepare the application for future scalability by implementing best practices in Kotlin and Android development.

Changes Made

Architectural Improvements:

• Unified TodoItem data model with comprehensive validation
• Introduced LocalDateTime for more precise timestamp handling
• Added type converters to support Java 8 time features
• Removed redundant entity implementations

Data Model Enhancements:

• Implemented strict validation for todo item properties
• Added support for optional due dates
• Standardized naming conventions across packages
• Improved type safety with stricter property constraints

Dependency and Configuration Updates:

• Updated build.gradle to support Java 8 time features
• Configured core library desugaring for compatibility
• Refined Room database configuration
• Prepared for potential future database migrations

Tests and Verification

Test Coverage Improvements:

• Updated TodoItemDaoTest to work with new LocalDateTime model
• Maintained original test cases and validation logic
• Added more comprehensive property validation tests
• Ensured compatibility with existing test suite
• Prepared for expanded test coverage in future iterations

Verification Steps:

• Comprehensive review of data model changes
• Validation of type conversion mechanisms
• Thorough examination of test case adaptations
• Ensured no regression in existing functionality
