test: add comprehensive integration tests for custom attributes array support
- Add array attribute endpoints to both .NET Framework and .NET Core test applications - Create integration test classes for testing array serialization end-to-end - Test string, int, and bool arrays in transaction traces and events - Verify empty arrays and null-only arrays are properly skipped - Test null filtering within arrays (nulls are excluded from serialized arrays) - Support both ASP.NET Framework (WebAPI) and ASP.NET Core applications - Add remote service fixture methods for exercising array endpoints - Fix test reliability by using transaction events for multi-endpoint scenarios Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
