fix: provide application for service trace dashboard

[dodjdnh]

Summary

Query provider metadata for the current service using its mesh, interface, version, and group, then resolve ProviderAppName. Generate the Service Trace dashboard URL with var-application=<ProviderAppName> and var-service=<Interface> only when the provider application is unique and reliable.

Return an error if metadata lookup fails, metadata is absent, the application is missing, or multiple distinct applications are found. Multiple metadata entries with the same application are deduplicated. The fix does not arbitrarily select the first provider or rely on Grafana's saved default. Service Metric URL construction is unchanged, and Go regression tests cover the behavior.

Verification

go test ./pkg/console/service ./pkg/console/handler: PASS.

Real end-to-end check	Result
Application Trace	PASS
Service Trace	PASS
Application Metric	PASS
Instance Metric	PASS
Service Metric	PASS

For Service Trace, the variables generated by Dubbo Admin were used in a live Grafana/Jaeger query that returned the newly generated trace. Instance Metric retains its existing IP:QoSPort semantics. Instance Trace has a separate known issue and is not changed by this PR.

The external end-to-end verifier sends a real /login request and finds its UserService/login trace in Jaeger. It then calls Dubbo Admin's Trace dashboard API, reads the actual URL and live Grafana dashboard query template, and executes the Grafana Jaeger query using Admin's variables. It reports PASS only if the query returns the same new trace ID.
