The pagination toggle read its rollback baseline off the `servers` entry,
which only advances on a successful `GET /api/servers`. Once a list read
fails that entry describes disk as it was before every write made since,
so the #1721 rollback reverted to a value nothing on disk holds — and
clearing the optimistic override fell back to the same stale entry, so
the UI was wrong from both directions.
Remember the last settings write known to have landed (a new gated hook,
`useLastPersistedSettings`) and roll back to that instead, keyed to the
`servers` entry it was derived from so a fresh list read supersedes it.
Both settings writers — the toggle and the settings modal's debounced
persist — feed the one record.
Closes#2089
