As an API consumer, I want to receive informative and standardized error responses for REST and GraphQL endpoints so that I can handle errors gracefully and provide feedback to the end-users.
Acceptance Criteria
[ ] Both REST and GraphQL endpoints must return appropriate HTTP status codes.
[ ] GraphQL errors must include 'message', 'locations', 'path', and 'extensions' fields according to the spec.
[ ] REST responses must include 'code', 'message', 'details' fields in their error responses.
[ ] Errors are logged with sufficient detail for debugging by API maintainers.
[ ] Rate limiting errors should provide information on when to retry.
[ ] API should support internationalization (i18n) for error messages.
[ ] Errors must not expose implementation details that could lead to security vulnerabilities.
