Owen Lin e0a3641e6c Support paginated thread history in app-server list APIs (#33152) ...

## Why

Clients could discover threads with paginated history, but could not page their
turns through `thread/turns/list`.

## What changed

- Route `thread/turns/list` for paginated threads through the thread store,
  preserving cursors, sort direction, turn status, timing, errors, and the
  requested `summary` or `notLoaded` item view.
- Reject the `full` turn item view for paginated threads and direct clients to
  `thread/items/list` for complete item pagination.
- Return each item page entry with both its containing `turnId` and `item`, so
  clients can regroup thread-wide pages into turns.
- Expose local thread-store turn and item pagination through the `ThreadStore`
  implementation.

## Testing

Added app-server coverage for paging projected turns and items, item views,
cursors, turn metadata, and rejection of the unsupported `full` view.
