feat(cli): Add intervals list command to CLI

- Created `src/imednet/cli/intervals/__init__.py` to register a `list` command for intervals using `register_list_command`.
- Bound the intervals command to the `intervals` attribute of the SDK, exposing `interval_id`, `interval_name`, and `interval_sequence`.
- Registered `intervals_app` as a Typer subcommand in the root `src/imednet/cli/__init__.py`.
- Added unit tests `test_intervals_list_success` and `test_intervals_list_empty` to ensure the command correctly interfaces with the SDK and prints output.
- Formatted and statically typed.
