feat: implement unified certificate persistence system

- Add SetCertificate method handling all Cardano certificate types
- Switch interface from slot to ocommon.Point for consistency
- Add comprehensive test suite with 19 test cases
- Remove deprecated certificate setter methods
- Include certificate mapping model and migration updates
