Refine onboarding model setup flow

Remove composer blocking so sends always create or enter a chat and route missing-model messages through the in-thread gate.

Make Utility model selection explicit by removing same-as-main sync and defaulting to each provider's utility model when available.

Compact onboarding success channel cards and update static regressions for the new onboarding/gate behavior.
