fix(dashboard): pass missing args to encryptionPct in refresh()

Commit eb5ea3b generalised encryptionPct from (transport) to
(data, encryptedKeys, allKeys) and updated renderTransport and
renderUpstreamWire, but missed the call inside render() that computes
the inline `~N/s · M% enc` QPS tag. With undefined allKeys, the
first .reduce() threw TypeError and the render try/catch silently
downgraded the whole dashboard to "disconnected" — every panel left
empty even though /stats was returning real data.

Fix the call site to match the other two (inbound-wire keys) and have
the catch log to console so the next silent-failure regression shows
up in DevTools within seconds instead of a source dive.
