refactor: rename openhis → healthlink-his (complete rebranding)

- Maven modules: openhis-* → healthlink-his-*
- Java packages: com.openhis → com.healthlink.his (3,278 files)
- Configuration: context-path, DB schema, logger, package scan
- Frontend: API paths /openhis/ → /healthlink-his/ (30 files)
- Database: healthlink_his schema with 188 tables (copied from hisdev)
- Verified: 18/18 API tests passed, 10-concurrent smoke test passed
