• Removed unused ITracingService dependency from UserCreatedEventHandler.
• Streamlined email verification logic with improved exception handling and logging.
• Updated EmailService to URL-encode the verification token for better link handling.
• Added OpenTelemetry sink configuration in SerilogExtensions for structured logging to Aspire Dashboard.

Summary by CodeRabbit

Walkthrough

The pull request refactors the tracing and logging architecture by removing tracing dependencies from event handlers, consolidating OpenTelemetry resource configuration across tracing and logging pipelines, integrating an OpenTelemetry sink into Serilog, and adding URL encoding for email verification tokens.

Changes

Cohort / File(s)	Summary
Event Handler Simplification src/Application/EventHandlers/UserCreatedEventHandler.cs	Removed ITracingService dependency and associated activity/tracing code from constructor; simplified nested try/catch to single try block; retained token generation and email sending flow with logging.
Email Service Enhancement src/Infrastructure/Services/Email/EmailService.cs	Added WebUtility.UrlEncode() encoding for email verification token in verification URL construction.
OpenTelemetry Configuration src/Web.Api/Extensions/OpenTelemetryExtensions.cs	Refactored to use unified ResourceBuilder for both tracing and logging; introduced centralized OTLP endpoint variable with http://localhost:4317 fallback; reordered EF Core instrumentation before ASP.NET Core; updated console/log messages to reflect tracing context.
Serilog OpenTelemetry Integration src/Web.Api/Extensions/SerilogExtensions.cs	Added OpenTelemetry sink to Serilog configuration; reads OTLP endpoint from OTEL_EXPORTER_OTLP_ENDPOINT environment variable with fallback; sets resource attributes (service.name, service.version, service.namespace).
Project Dependencies src/Web.Api/Web.Api.csproj	Added Serilog.Sinks.OpenTelemetry (v4.1.0) NuGet package reference.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Verify that URL encoding for verification tokens does not break token validation logic or existing integration tests
• Validate that unified OTLP endpoint and ResourceBuilder configuration correctly applies to both tracing and logging pipelines without duplication
• Confirm that Serilog OpenTelemetry sink integrates cleanly with existing Console and File sinks
• Review event handler simplification to ensure removal of tracing does not impact observability requirements

Poem

🐰 A rabbit hops through telemetry streams,
Encoding tokens in digital dreams,
With Serilog sinks and resources aligned,
The traces now shine, refined and designed!
No tracing clutter clutters the way—
Clean handlers dance on this blessed day! ✨
