test: add tests for parse_site_location edge cases

Added unit tests to `tests/unit/test_cli/test_http/test_api/test_site_location.py` to cover `parse_site_location`. The tests cover standard string format, string containing spaces, exceptions handling incorrect lengths (too few or too many parameters), incorrect coordinate formats (non-float characters), and empty strings.
