WIP: complete modular architecture refactor

- Reorganize entire codebase into feature-based modular architecture
- Move presentation components to feature modules (home, settings, statistics)
- Separate core functionality into dedicated modules (data, database, network, domain, model, ui, designsystem, datastore)
- Restructure navigation with renamed SofiaTrackerNavHost and updated routing
- Update all import statements across modules to reflect new package structure
- Configure build dependencies and module relationships for clean architecture
- Move Hilt modules to appropriate core modules (database, network, data)
- Update all ViewModels, repositories, and use cases with new namespacing
- Refactor UI components and screens to use modular design system

This represents a major architectural improvement for better separation of concerns,
testability, and maintainability following Android's recommended app architecture patterns.
