Class WorkspaceInitializerService

Classify errors into actionable types Replaces AppComponent error handling logic

Handle authentication retry with backoff Replaces AppComponent.handleAuthRetry() logic

Initialize workspace with authenticated user Replaces all the logic from AppComponent.handleLogin()

True when the error describes the transport failing rather than the server refusing.

One definition, shared with the metadata provider in @memberjunction/core (CoreIsTransportError), so a shape that counts as transport for the bootstrap banner counts as transport for the provider's cache fallback too — and a refusal (a key without the scope, a user without the role) is "not transport" in both places.

Static and public so the classification can be tested directly and reused without standing up the service's four injected dependencies.
