Summary

Add Saving Goals Management, allowing users to create financial goals, track saving progress, and manage contribution history.

Key Changes

• Add CRUD, archive, and restore APIs for saving goals.
• Add list, create, update, and delete APIs for contributions.
• Calculate saved amount, remaining amount, progress percentage, remaining days, and overdue status.
• Automatically synchronize ACTIVE, PAUSED, and COMPLETED statuses.
• Protect all resources with authentication and user ownership checks.
• Use Serializable transactions when updating contributions and goal progress.
• Lock goal currency after the first contribution to preserve reporting consistency.
• Add Prisma models, constraints, indexes, and database migration.
• Update Swagger documentation for all Saving Goals endpoints.
• Update project memory with the new module decisions.

Notes

• Contributions are tracked independently and do not modify wallet balances.
• The database migration is included but was not applied automatically.
