feat: implement tenant suspension handling and deletion functionality

- Added a new tenant suspension page and related components to inform users when their tenant is suspended due to policy violations.
- Implemented deletion functionality for tenants in the SuperAdminTenantManager, allowing super admins to permanently delete tenant accounts.
- Updated localization files to include new strings for tenant suspension and deletion prompts.
- Enhanced the DataManagementService to handle tenant deletion with metadata checks.
