- confirmRegistration: wrap auto-login in separate try-catch so a failed
login after confirmation never shows as 'wrong code' to the user.
If auto-login fails, user is sent to LoginScreen to log in manually.
- SessionManager.login: always reconnect fresh (disconnect + enableReconnect
+ connect) instead of reusing the stale post-registration TCP connection.
Fixes login failures caused by server closing the registration connection.
