v0.05: fix Roundcube autologin + hamburger menu focus

Roundcube autologin fix:
- Added missing session->regenerate_id(false) and session->set_auth_cookie()
  calls after login, matching Roundcube's normal login flow in index.php.
  Without these, the roundcube_sessauth cookie was never set, causing every
  second request to fail with 'session is invalid or expired'.

Hamburger menu fix:
- Added activateWindow() + raise_() + processEvents() before menu.exec_()
  to ensure the toolbar window is active before the QMenu event loop starts.
  Without this, WA_ShowWithoutActivating prevents focus from being grabbed
  and the menu vanishes immediately.
- Added try/except to surface any silent errors.
