Subject: [PATCH 1/2] fix(dashboard): show QR loading state immediately and
 keep polling until ready
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When Chromium is still initializing, getQR returns an error before the
QR is available. The previous code caught that error, set a global error
banner, and stopped — leaving the user with no way to scan without
manually retrying.

This fix opens the QR modal in a loading state as soon as the user
triggers Reconnect/Start, so the existing 5-second polling interval
starts immediately. The interval now keeps running on transient errors
(QR not ready yet) and only stops when the session itself reaches a
terminal state (failed/disconnected) or when the QR is successfully
scanned (status: ready).
