This commit brings System Settings in line with Payment Settings and
prepares the whole component for multi-language deployments.
Key points
----------
• Introduced a “General Settings” card in `SystemSetting.js`
- Adds a `ServerAddress` field (copied from Payment Settings).
- Explains that this URL is used for payment callback & default homepage.
- Implements `submitServerAddress` to persist the option.
• Internationalisation
- Imported `useTranslation` and wrapped **all** Chinese UI strings in `t()`.
- Localised section titles, labels, placeholders, banners, buttons,
modal texts and toast messages.
- Dynamic banner/tool-tip descriptions now combine `t()` fragments with
template literals for runtime URLs.
• UX improvements
- Added contextual `extraText` under the ServerAddress input.
- Ensured placeholders like “sensitive info…” are translatable.
With these changes, administrators can configure the server URL from the
System Settings tab, and the entire page is ready for seamless language
switching via the existing i18n framework.
Restructure payment settings into a separate tab for better organization and user experience. The changes include:
1. Create dedicated Payment components in the Setting directory structure
2. Move payment-related settings from SystemSetting to PaymentSetting
3. Add proper i18n support with useTranslation hook
4. Split payment settings into GeneralPayment and PaymentGateway components
5. Fix internationalization issues in placeholder text
6. Update navigation with CreditCard icon for payment tab
This refactoring improves code maintainability by following the established project pattern of having specialized setting components in their own directories.
