hailin 5447545486 fix(contribution): move calculateForAdoption out of CDC transaction
Root cause: calculateForAdoption uses separate DB connections, which
cannot see uncommitted data in Serializable isolation level, causing
"Adoption not found" errors.

Solution (following Kafka Idempotent Consumer best practice):
- Add TransactionalCDCHandlerWithResult<T> type for handlers with return
- Add withIdempotencyAndCallback() wrapper for post-commit callbacks
- Add registerTransactionalHandlerWithCallback() registration method
- AdoptionSyncedHandler.handle() now returns AdoptionSyncResult
- Contribution calculation runs AFTER transaction commits via callback
