📝 Changes description

This PR refactors the entire src/services structure by moving all domain-specific services into their respective module folders under src/modules/<domain>/application/services. All dependent imports across the codebase have been updated accordingly. In addition, unit tests were added or migrated to src/modules/<domain>/__tests__/services/ for each affected service to ensure consistent functionality. Once the migration was complete, the old src/services folder was deleted. This change enforces the DDD (Domain-Driven Design) structure and improves maintainability.
