[Copilot]

This PR updates various NuGet package dependencies to their latest compatible versions while maintaining .NET 5.0 compatibility and ensuring the solution continues to build without breaking changes.

Security Improvements

The following critical security vulnerabilities have been resolved:

• MongoDB.Driver: Updated from 2.11.6 to 2.28.0 - resolves multiple high and moderate severity vulnerabilities
• Azure.Storage.Blobs: Updated from 12.8.0 to 12.19.1 - resolves moderate severity vulnerability
• Microsoft.AspNetCore.Authentication.JwtBearer: Updated from 5.0.2 to 5.0.17 - resolves moderate severity vulnerability
• System.Data.SqlClient: Updated from 4.8.2 to 4.8.6 - partial improvement (latest available for .NET 5.0)

Package Updates

Major Updates

• Microsoft.Azure.CognitiveServices.Personalizer: Kept at 1.0.0 (latest available)

Compatibility Notes

The solution has been tested and builds successfully with all updates. Some packages were intentionally kept at their current versions to avoid breaking changes that would require significant code modifications:

• SixLabors.ImageSharp versions 1.0+ introduce namespace changes and API modifications
• CsvHelper versions 15+ have breaking constructor and API changes
• All Microsoft packages maintain compatibility within the 5.x version range

Build Status

✅ Build successful - All updates maintain compatibility with existing code
✅ No breaking changes - Solution builds without modification
⚠️ Some vulnerabilities remain - SixLabors.ImageSharp vulnerabilities persist due to compatibility constraints

Fixes #1010.
