chore(ui): drop unreachable reset dialog test and stale provider comment

The Reset connection button only appears on the confirmation step, which
itself only renders when the enterprise connection exists, so the missing
connection branch is not reachable in practice. Removes the matching test
and the stale provider setter JSDoc that no longer describes the flow.
