fix(todo-continuation-enforcer): preserve model/provider from nearest message

When injecting continuation prompts, extract and pass the model field

(providerID + modelID) from the nearest stored message, matching the

pattern used in background-agent/manager.ts and session-recovery.

Also updated tests to capture the model field for verification.
