feat(core): add note editing functionality

- Updated `edit_user.py` to accept a `--note` argument, allowing user notes to be modified or cleared.
- Extended the `edit-user` command in `cli.py` with a `--note` option.
- Modified the `edit_user` function in `cli_api.py` to pass the new note argument to the underlying script.
