Handle all 2xx HTTP status codes as success

[IFAKA]

Problem

The response handler only treats HTTP 200 as success:

if response.status_code == 200:
    return data

This means valid success responses like 201 (Created), 202 (Accepted), or 204 (No Content) are incorrectly treated as errors and raise APIError.

Fix

Use response.ok which returns True for any 2xx status code:

if response.ok:
    return data

Test

✓ 200 OK: Returned data correctly
✓ 201 Created: Returned data correctly
✓ 202 Accepted: Returned data correctly
✓ 204 No Content: Returned data correctly
✓ 400 Bad Request: Raised ValidationError correctly
✓ 401 Unauthorized: Raised AuthenticationError correctly
✓ 500 Server Error: Raised APIError correctly
