Add integration tests for the Branch development ETL pipeline: - BranchDevEtlTests with tests for pipeline creation and execution - Tests verify pipeline creates correctly and loads data from cache files - Added appsettings.json with local connection string and cache directory - Added necessary packages (Configuration.Json, SqlClient, Dapper) Tests require local SQL Server and CACHED_DB_FILES directory with branch.json.zstd to pass; tests silently skip if resources unavailable.
