Create missing VnfOperationVO and VnfService interface

VnfOperationVO:
- JPA entity for vnf_operations table
- Tracks operation ID, rule ID, status, timestamps
- Full getter/setter implementation

VnfService interface:
- findOperationByRuleId() method
- listDictionaries(), uploadDictionary()
- testConnectivity(), reconcileNetwork()
- Fixes 20+ compilation errors
