Objective

This PR addresses the need to align the Windows agent's user interface with our branding and usability standards. The change involves updating the title in the win32ui.rc file from "Wazuh Agent Manager" to "Wazuh Agent". This modification aims to simplify the naming and improve user recognition and consistency across our platform interfaces.

Description

• User feedback and internal reviews have suggested that the title "Wazuh Agent Manager" may lead to confusion, as it implies a broader management functionality than is provided by the standalone agent application. To clarify the purpose and streamline the user experience, we propose changing the title to "Wazuh Agent".
• The modification was made in the win32ui.rc resource file, which handles the user interface elements of the Windows agent. This change is purely textual and does not affect the functionality of the agent or the UI beyond the window title.
