Roll back the interaction mode when Implement fails.

For an existing Plan thread with the legacy setting disabled, a failed Implement request can leave both the server and draft modes in Build ("default"). The failure path restores the previous composer content but not its mode. This hides the Plan follow-up controls, prevents retry through the plan-association path, and leaves a blank Implement action with no implementation prompt restored.

Restore the prior Plan mode in both the server thread and composer draft when startThreadTurn fails.

Review comment at @apps/web/src/components/ChatView.logic.ts around lines 545 -
551:
Update the failure path for startThreadTurn so a failed Implement request in an
existing Plan thread restores Plan mode in both the server thread and composer
draft, including when the legacy plan setting is disabled. Preserve the existing
composer-content restoration and ensure the Plan follow-up and retry paths
remain available.
