When elevatedAllowed is false (e.g., for heartbeat surface which isn't
in any allowFrom list), the elevated level was incorrectly defaulting
to 'on', causing bash commands to fail with 'elevated is not available'.
Now defaults to 'off' when elevated isn't allowed, so bash works
normally without trying to use elevated mode.
Fixes: https://github.com/clawdbot/clawdbot/issues/181
Previously, if the gateway was unreachable (wrong IP, offline, etc.),
the Android app would crash with an unhandled socket exception.
Changes:
- Wrap socket.connect() in try/catch to handle connection failures
- Return PairResult with error message instead of crashing
- Display actual error message in status text instead of generic 'pairing required'
This gives users useful feedback like 'Connection refused' or
'Network is unreachable' instead of a crash.
