feat: improved error message and updated error code for PrintTopics command

[stevenpyzhang]

Description

print <topic> returns a 200 response with a not too specific error message when trying to print a topic the user doesn't have Read permissions for. Updated to return 403 response, 40301 error code, and a more specific error message.

Old response
Not authorized to access topics: [qwerqwerqwerqwerqtly]

New response

{
    "@type": "generic_error",
    "error_code": 40301,
    "message": "Authorization denied to Read on topic(s): [qwerqwerqwerqwerqtly]",
    "stackTrace": []
}

Testing done

Reviewer checklist

• Ensure docs are updated if necessary. (eg. if a user visible feature is being added or changed).
• Ensure relevant issues are linked (description should include text like "Fixes #")
