Merge branch 'feature/check-cert-locker-before-acme' into test/proxy-fixes

Capture engine reference before actCancel() in cleanupConnection().

After actCancel(), the connectWithRetryRuns goroutine sets engine to nil,
causing connectClient.Stop() to skip shutdown. This allows the goroutine
to set ErrResetConnection on the shared state after Down() clears it,
causing the next Up() to fail.
