Block executor is still checking if a transaction should be skipped or not based on tx.meta.voided_by. It works fine for the actual execution but not for the dry run.

Motivation
Add HTTP API and CLI support for dry-running nano contract block execution without modifying state. This allows developers to inspect what would happen during NC execution for debugging and verification purposes.
Acceptance Criteria

master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
