feat(contracts): command to display contracts info

## Description

It will be helpful to have a command that displays contracts' information, like the local path, Code ID, address, and current metadata (if deployed on-chain).

## Technical Details

### `contracts show`

Displays information about a contract by its name or address.

#### Arguments

TBD

Start by reviewing the existing contract-related CLI commands and their argument patterns. Define how `contracts show` accepts a contract name or address, then confirm the expected output for local path, Code ID, address, and current on-chain metadata before implementation.
