fix(tests): add missing namespace imports for .NET test files

- SecurityTests.cs: Add using QuantEngine.Infrastructure.Data
  - IDbConnectionFactory reference now resolves correctly

- UnitTest1.cs: Add using QuantEngine.Core.Infrastructure
  - OperationalReportLoader reference now resolves correctly
  - Update full paths to use imported namespace (cleaner code)

All 214 unit tests now pass without errors.
