Review round 1 on #2091. A single record slot let a save on one server
discard the baseline a later failed write on another still needed — the
settings modal opens for any server, connected or not, so that sequence
reproduces #2089 through the very mechanism meant to prevent it. Records
are now kept per server id.
The record also paired with the `servers` entry captured when the write
was *issued*, so a list read landing while the write was in flight was
mistaken for one that happened after it and discarded a live record. It
now pairs with the entry as of completion, read through a ref (mirrored
in an effect — writing a ref during render is a `react-hooks/refs`
error). The residual — a read whose response predates the write but
arrives after it — needs a revision or ETag `useServers` does not
expose, and is documented on the hook.

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
