* This function dynamically generates a UI container with checkboxes for each style ID provided.
* It includes features such as:
* - A title bar with a minimize/expand button.
* - Checkboxes for selecting individual styles.
* - Shift-click functionality for selecting multiple checkboxes at once.
* - A "Select All" button to toggle the selection of all styles.
* - A "Sync Selected Styles" button to initiate the syncing process for selected styles.
* - A status display to provide feedback on the syncing process.
*
* The UI is appended to the document body as a fixed element, allowing users to interact with it regardless of page scrolling.
*
* @fires syncButton.onclick - When the "Sync Selected Styles" button is clicked, it triggers the syncing process for the selected style IDs.
* @fires selectAllButton.onclick - When the "Select All" button is clicked, it toggles the selection state of all checkboxes.
* @fires checkbox.onclick - When a checkbox is clicked, it updates the visibility of the "Sync Selected Styles" button based on whether any checkboxes are selected. It also handles shift-click selection.
* @fires minimizeButton.onclick - When the minimize button is clicked, it collapses or expands the form.
