Add FFmpeg updater module and GUI integration

Introduces a new FFmpeg updater module for checking and updating FFmpeg to the latest essentials build, with progress reporting and version comparison. Updates language files with new translation keys for the updater in multiple languages. Refactors Windows FFmpeg installation to use the new updater logic. Adds UpdaterTabWidget to the GUI dialogs for integration of the updater into the application's interface.
