Ensure daily automatic backups are performed upon user login

Introduce a daily automatic backup check and execution triggered upon successful user login, ensuring data consistency and safety across the platform. This includes a new `checkAndPerformDailyBackup` method in `backupService.ts` and its integration into the login process in `localAuth.ts` and `localAuth.production.ts`.
