fix: make TelemetryClient throw errors on auth failures to enable proper queue retry

- TelemetryClient now throws errors when authentication fails or session token is missing
- This allows the queue processor to properly identify failed sends and retry them later
- Fixes issue where telemetry events were being discarded when in inactive-session state
- Events will now be queued and retried when authentication is restored
