Add Artist entity with database migration, linting, and static analysis

[Copilot]

This PR adds a new Artist entity to the movie library application along with comprehensive CI/CD improvements for code quality and static analysis.

🎨 New Artist Entity

Added a new Artist model with the following properties:

• Id (Primary Key)
• Name (Required, max 100 characters)
• BirthDate (Required)
• Nationality (Optional, max 50 characters)
• Timestamp (Concurrency token)

The entity follows the same patterns as existing models like Director and includes proper Entity Framework configuration.

🗄️ Database Layer Updates

• Created migration 20241216230000_AddArtistTable.cs to add the Artists table
• Added Artists DbSet to RazorPagesMovieContext
• Configured entity relationships and constraints in OnModelCreating

🧪 Testing

Added comprehensive test suite ArtistTests.cs with:

• Unit tests for all entity properties
• Theory tests with multiple data scenarios
• Follows existing test patterns using xUnit

🔧 Linting & Code Quality

Enhanced the project with robust linting and static analysis:

• EditorConfig: Added .editorconfig with C# formatting rules for consistent code style
• Static Analysis: Integrated Microsoft.CodeAnalysis.NetAnalyzers and StyleCop.Analyzers
• Configuration: Added stylecop.json for customized analyzer settings
• Project Settings: Enabled enhanced analysis mode and code style enforcement

🚀 CI/CD Improvements

Updated the CI workflow to include static analysis reporting:

• Added step to count and report analyzer warnings
• Provides visibility into code quality metrics
• Uses GitHub Actions notices for better feedback
• Maintains existing CodeQL analysis

Example Usage

// Create a new artist
var artist = new Artist 
{
    Name = "Leonardo DiCaprio",
    BirthDate = DateTime.Parse("1974-11-11"),
    Nationality = "American"
};

// Add to database context
context.Artists.Add(artist);
await context.SaveChangesAsync();

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.microsoft.com
  • Triggering command: wget REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
