[STYLE] 更新 Favicon 與側邊欄品牌標誌

1. 使用 Pillow 將新品牌 Logo 自適應裁切並生成 512x512 PNG 格式的 starcloud_icon.png。
2. 生成包含多種主流尺寸（16x16 至 256x256）的全新 favicon.ico。
3. 於後台管理主模板 (admin.blade.php) 與登入視圖 (login.blade.php) 中加入 Favicon 宣告。
4. 替換後台主模板 (admin.blade.php)、全螢幕載入畫面 (loading-screen.blade.php) 以及 Logo 元件 (application-logo.blade.php) 中所有舊的 S1_cropped_transparent.png 為全新星雲品牌 icon。
