Enhance error handling in OxiAPI and Node classes

- Updated the `reload` method in the `OxiAPI` class to catch `HTTPError` exceptions and raise a custom `OxiAPIError` with context.
- Improved the `__call__` method in the `Node` class to handle `HTTPError` exceptions similarly, providing context-specific error messages.
- Introduced a new class method `from_http_error` in `OxiAPIError` for standardized error message generation based on HTTP status codes.
