Introduced Docker Compose configurations for Citus and YugabyteDB clusters and updated connection strings in `appsettings.json`. Modified `Program.cs` to enable Entity Framework Core support for both databases and updated the `SqlDatabaseProvider` enum accordingly. Adjusted the Docker Compose setup and bumped `Yarp.ReverseProxy` package version.
Upgraded SQL Server image to 2022-latest and aligned environment variables for clarity. Replaced hardcoded host directory with a named volume for SQL Server data to improve portability. Added `restart: unless-stopped` policy for better container management.
