Fix: Ensure Home key moves cursor to start of filename during rename

This commit addresses the issue where pressing the Home key during file renaming in List View (and other views inheriting from BaseGroupableLayoutPage) did not move the cursor to the absolute beginning of the filename if the filename was longer than the visible TextBox. The fix ensures that textBox.SelectionStart is set to 0 and textBox.SelectionLength is set to 0 when the Home key is pressed, providing behavior consistent with Windows Explorer.
