This PR addresses naming inconsistencies throughout the codebase and provides comprehensive documentation to improve the developer experience.

Issues Fixed

Naming Consistency

The project had several naming inconsistencies that have been standardized:

1. Health Check Descriptions: Fixed typos and inconsistent naming in Startup.cs

   • "Northwinds databse Health check" → "Northwind database Health check"
   • Fixed both spelling ("databse" → "database") and standardized naming

2. Database Script References: Corrected filename case inconsistencies

   • PowerShell and shell scripts referenced InsertNorthwindsDefaultData.sql but the actual file is InsertNorthWindsDefaultData.sql
   • Updated both init-database.ps1 and Init-database.sh

3. SQL Script Comments: Standardized database name references in comments

   • Updated main SQL schema file comments to use consistent "NorthWinds" naming
   • Updated test SQL file comments to match project conventions

Documentation Enhancement

Added a comprehensive README.md that includes:

• Architecture Overview: Clear explanation of the clean architecture pattern and project structure
• Technology Stack: Complete list of frameworks and tools used (.NET 8.0, EF Core, etc.)
• API Documentation: Detailed endpoint descriptions with example curl commands
• Setup Instructions: Step-by-step local development setup with database configuration
• Build & Deployment: Both local and Docker deployment options
• Testing Guide: How to run different test categories and interpret results
• Configuration: Environment variables and application settings documentation
• Troubleshooting: Common issues and their solutions
• Development Guidelines: Best practices and code organization principles

Technical Details

The changes maintain full backward compatibility:

• All 24 existing tests continue to pass
• No functional code changes were made to core business logic
• Only corrected obvious typos and inconsistencies in descriptions/comments
• Preserved the existing "NorthWinds" naming convention used throughout the codebase

The project now provides a professional developer experience with clear documentation and consistent naming, making it easier for new contributors to understand and work with the codebase.
