alexsong-oai 41d3dc56a0 Surface model provider authentication recovery progress (#41239) ...

## What changed

- Emit turn-scoped authentication recovery started and completed events when a model provider refreshes expired credentials.
- Add stable `modelProvider/authRecoveryStarted` and `modelProvider/authRecoveryCompleted` app-server notifications with the thread, turn, provider, and user-facing message.
- Show recovery progress in the TUI and `codex exec`, including Amazon Bedrock session reauthentication.

## Testing

- Cover provider recovery success and failure events, app-server routing, client rendering, and Amazon Bedrock credential refresh.
