eknight-oai b337fe06b7 Defer agent mail after empty final answers (#56133) ...

## Why

An explicit `final_answer` with empty or whitespace-only text could allow queued agent mail to restart the turn instead of leaving it queued for the next turn.

## What changed

Treat explicit `final_answer` messages as terminal regardless of visible text in both completed-item handling and turn-item finalization. Untagged messages still require visible text to defer mailbox delivery; `commentary` and `partial_answer` messages do not defer it.

## Testing

Extend regression coverage for empty and whitespace-only final answers, delivery of queued agent mail on the next turn, and message board notifications arriving before or after an empty final answer.
