refactor(member, auth): streamline product info retrieval and enhance dashboard statistics

- Updated `getProductInfo` method in `Member` model to use a unified model for fetching product data.
- Refactored `logLogin` method to utilize `MemberLoginLog` for logging login attempts.
- Introduced `getDashboardStats` method in `AuthService` to gather user-specific statistics, including remaining quotas and counts of authorized accounts, published tasks, and works.
- Added new database configuration for Douyin business statistics.
