Fix status flicker during WebSocket reconnect loop

connect() was unconditionally calling setStatus('connecting', ...) at the
top of each attempt, which flickered over "Disconnected — retrying..."
every 3 seconds during the retry loop.

Fix: only show "Connecting..." on the very first attempt (everConnected
is false). Once a connection has been established, preserve the
"Disconnected — retrying..." state across all subsequent reconnect
cycles until onopen fires. Also reset everConnected on Save so pointing
at a new server correctly shows "Connecting..." from a clean slate.
