Fix: WhatsApp instance search trigger

The instance search was incorrectly triggered on every keystroke in the instance name input field. The fix ensures that the search uses the saved instance name from local storage, and is only triggered when the "Conectar WhatsApp" menu is opened. The instance name input field is now only used for creating new instances.
