Style/RuboCop: Finalize YARD documentation and fix lints in Core/Modules dispatchers

[Ganesh-abc]

This PR focuses on improving YARD documentation for command dispatcher components as part of issue #21142.
Working on these files also helps me better understand the dispatcher architecture for my GSoC proposal.

This PR achieves 100% RuboCop compliance and adds comprehensive YARD documentation for the Core and Modules command dispatchers.

Key Changes:

• Added YARD-style documentation to methods in lib/msf/ui/console/command_dispatcher/core.rb and lib/msf/ui/console/command_dispatcher/modules.rb.
• Fixed over 6,000 combined line offenses related to layout, indentation, and Ruby style guide standards.
• This cleanup ensures a modern, readable foundation for the command layer, supporting my GSoC 2026 proposal for automated environment provisioning.
