fix: allow MiniKit auto-connect to retry after disconnect

[jaffarkeikei]

Summary

Fixes #2596

The AutoConnect component was only attempting to connect once due to the hasAttemptedConnection ref never being reset. After a user disconnects in Base App, the ref would remain true, preventing auto-connect from running again — causing the Connect button to do nothing.

The Problem

// This ref is set to true on first connect attempt and never reset
hasAttemptedConnection.current = true;

After disconnect:

1. User taps Connect
2. hasAttemptedConnection.current is still true
3. Early return prevents auto-connect
4. Connect button appears to do nothing

The Fix

Reset hasAttemptedConnection when the user disconnects:

useEffect(() => {
  if (!isConnected && !isConnecting) {
    hasAttemptedConnection.current = false;
  }
}, [isConnected, isConnecting]);

Testing

Added test case: "should attempt reconnection after disconnect" that verifies:

1. Initial auto-connect works
2. After simulating connect → disconnect cycle
3. Auto-connect runs again (connect called twice total)
