Refactor and centralize UI panel visibility logic

Consolidates the logic for showing and hiding UI elements into dedicated functions, `Update-DriverDownloadPanelVisibility` and `Update-OfficePanelVisibility`.

This change simplifies the event handlers for the "Download Drivers" checkbox by using a single handler for both checked and unchecked states. It also moves the initial UI setup from the main script into the core initialization module, improving code organization and reducing duplication.
