This PR fulfills the requirements of #9069 by: - Adding a golangci-lint directive (forbidigo) to disallow all fmt.Errorf usages. - Replacing existing fmt.Errorf instances with structured errors from github.com/SigNoz/signoz/pkg/errors for consistent error classification and lint compliance. - Verified lint and build integrity.
