Initial project setup with domain, UoW, and API structure

Added .gitignore, solution, and project files for .NET 10. Introduced AGENTS.md and PLAN.md for guidelines and planning. Implemented appsettings.json, launchSettings.json, and MySQL config. Created AppDBContext and all domain models with composite keys. Added IUnitOfWork and EFUnitOfWork. Structured feature folders for Region, Route, Vehicle, Store, Warehouse, and Order with DTOs, repositories, services, and controllers. Added initial EF Core migrations and sample HTTP request. Registered dependencies and enabled OpenAPI in development.
