test: use module CLI in all commands and add unit test in pop-cli crate

[AlexD10S]

This PR refactors all pop-cli commands to use the CLI module introduce in this PR #216, enabling us to test the output messages produced by the CLI.
Additionally, tests have been added to ensure better coverage in the pop-cli crate. As a result, the test coverage of pop-cli has increased significantly, from 34% to 67% with overall project coverage now nearing our goal: 80%.

Coverage still can be improved, particularly the final parts of the install, build, and up commands, which are difficult to mock for a unit test.

Note: The call command does not include tests because they are being addressed in parallel in this PR #306 to avoid duplication of work.
