Owen Lin f950a1ba0b Preserve thread names during rollout migration (#39273) ...

## Why

Legacy threads and paginated threads read their displayed names from different metadata. Moving a rollout to paginated history must carry over its legacy-visible name so renamed threads do not lose it.

## What changed

- Load legacy indexed names once for an apply run.
- When promoting a thread, preserve an existing canonical name or copy its distinct legacy title, falling back to the legacy name index.
- Repair missing names when migration encounters an already-paginated rollout.

## Testing

Added migration tests covering preservation from both legacy name sources and repair on a rerun.
