Pull request overview

This pull request removes the NetworkRunnable trait abstraction and replaces it with direct execute methods on command structs. The goal is to simplify the code and make control flow easier to follow.

Changes:

• Removed the NetworkRunnable trait definition and all its implementations
• Replaced run_against_rpc_server method with execute method for each command
• Updated all commands to pass parameters directly instead of using Option wrappers
• Updated test utilities to call execute methods directly
• Refactored two unrelated methods in container/start.rs for better readability
