test(ui): pin who may record an explicit Default effort

Nothing covered ModelControls, which is where the effort restore decides
between "the user chose Default" and "nothing was found". Three cases: a
concrete effort in the session history is restored, history without an effort
records no choice, and a preserved manual override keeps a recorded Default.
The middle one fails on the previous commit's parent — it recorded `null` and
then `undefined` for the same restore.

Also drops the `fetchAll` binding GitView stopped using when the post-bootstrap
refresh moved to a forced `fetchStatus`; it was failing `bun run lint:ui`.
