fix(ui): reduce reconnect requests

- Add checks to the "recovery" logic for socket connect events to reduce the number of network requests.
- Remove the `isInitialized` state from `systemSlice` and make it a nanostore local to the socketConnected listener. It didn't need to be global state. It's also now more clearly named `isFirstConnection`.
- Export the queue status selector (minor improvement, memoizes it correctly).
