Incoming session verification request

Add more log to the state machines
Ensure the block cannot be cancelled, else if the Rust SDK emit a new state during the API execution, the state machine may cancel the api call.
Let VerificationFlowState values match the SDK api for code clarity.
Rename sub interface for clarity.
Migrate tests to the new FakeVerificationService.
