fix: fallback to any known node when control node not found by endpoint

dkropachev · dkropachev · commit 2a6fb7c3b888 · 2026-03-19T14:11:57.000-04:00
When the control connection endpoint doesn't match any node in metadata
(e.g. with PrivateLink or proxy setups), fall back to the first available
node instead of immediately throwing an exception.
