Enhancements for ark-cli Crate

[tareknaser]

• Focus only on printing output. Doesn't manage index.
• Use methods from other crates within the workspace to perform other tasks.
• Organize code into folders resembling subcommands.
• Each command file should have its own parameters and implement a handle method.
• Avoid handling printing specifics in main.rs.
• Add help messages are available for each command, subcommand, parameter, and flag.
• Format command output lists into tables where possible, using comfy_table crate.
• Implement an output-json (j) flag for commands where applicable.
• Avoid using unwrap() or expect() to prevent crashes.
