feat: move brand name to one config and redesign the accounting card

اپ: نام برند در همه‌ی صفحه‌ها و پیام‌ها یکسان شده و از یک تنظیم مرکزی خوانده می‌شود.
اپ: کارت حسابداری در صفحه‌ی مشتری بازطراحی شد؛ مانده‌ها و وضعیت لینک واضح‌تر نمایش داده می‌شوند.
پنل: کارت حسابداری در پرونده‌ی مشتری بازطراحی شد؛ مانده‌ها، آخرین ارسال و فرم لینک دستی واضح‌تر شده‌اند.
پنل: ستون «کد» در جدول‌ها به‌طور پیش‌فرض پنهان است و از انتخاب ستون‌ها قابل نمایش است.
پنل: تغییر نمایش ستون‌ها در جدول‌ها بلافاصله اعمال می‌شود.
