Move UpdateService and UpdateServiceImpl to OpenESPI-Common-java for proper architectural separation

- Moved UpdateService interface from DataCustodian to Common repository
- Moved UpdateServiceImpl implementation to Common repository
- Ensures all service implementations are centralized in OpenESPI-Common-java
- Maintains clean separation of concerns per Spring Boot 3.5 architecture
- Part of comprehensive architectural compliance improvements
