Dylan Hurd 1836ae0612 Preserve thread settings for goal-first and forked threads (#34469) ...

## Why

Goal-first and forked threads could create rollouts without recording their
effective thread settings. Resuming those threads after a restart could then
use current configuration instead of the settings selected when the thread was
created.

## What changed

- Persist a `thread_settings_applied` item when a goal first materializes a
  rollout, including a follow-up snapshot if settings changed concurrently.
- Append each fork's effective settings after its copied history so they take
  precedence over inherited settings during resume.
- Centralize conversion from `ThreadConfigSnapshot` to
  `ThreadSettingsSnapshot`.

## Testing

Added coverage that restarts the app server and verifies goal-first and forked
threads retain their respective `approvals_reviewer` settings.
