fix: i18n ephemeral policy keys + planning loading race (#2298)

## Summary
- Full Suite
[29642536622](https://github.com/Runfusion/Fusion/actions/runs/29642536622)
after #2297: shards 1–2 green; shard 4 i18n parity + shard 3
PlanningMode loading.
- Add `settings.general.ephemeralAgentTaskCreationPolicy*` to
zh-CN/zh-TW/fr/es/ko (FN-8265 keys were en-only).
- Gate the follow-up SSE question in the PlanningMode loading test so
`.planning-loading` is assertable before the next question arrives (CI
race).

## Test plan
- [x] `@fusion/i18n` parity + gate-coverage tests
- [x] PlanningModeModal loading-after-response test
- [ ] Full Suite all 4 shards green on main

## Summary by CodeRabbit

* **New Features**
* Added localized settings text for configuring ephemeral agent
follow-up task creation policies in Spanish, French, Korean, Simplified
Chinese, and Traditional Chinese.
* Added options to allow, require validation, or deny follow-up task
creation.

* **Tests**
* Improved planning mode loading-state test reliability with
deterministic synchronization.
