--chaos.monkey producing non-recoverable error

`return fmt.Errorf("monkey in the datacenter: %w: %v", consensus.ErrInvalidBlock, txTaskErr)`

`ErrInvalidBlock` - is not recoverable error. Node marking this block as bad and doesn't have other forks to switch. Probably need return some recoverable error. But anyway: current version is useful - for testing how node behave when doesn't have good forks.

Start by locating the --chaos.monkey implementation and the fmt.Errorf call shown in the issue. Trace how consensus.ErrInvalidBlock is classified and how fork handling treats it; the issue provides no file or test names, so confirm the intended recoverable-error behavior before changing anything. Done means the chaos mode's behavior is resolved and covered by the relevant existing test path.
