feat(dsp): Add missing notify methods on TransferProcessService

[ndr-brt]

What this PR changes/adds

Adds missing methods on TransferProcessService that will permit the DSP controller to ingest an incoming RemoteMessage to the service

Why it does that

refactoring

Further notes

• added processId to the TransferProcess*Messages through a TransferRemoteMessage interface
• applied an huge refactoring to the service, where every action creates a command than it gets validated first and applied later. the validation logic is duplicated in the service and in the command handler, this is needed because in the service we want to eventually give fast feedback to the client/counter part, and in the handler we want to ensure the validity of the command (as it is executed asynchronously). These logic could be refactored to a single one, a related issue will come.
