docs: fix README example snippets

[LocNguyenSGU]

Summary

Fix several README example issues that can break first-time onboarding.

Reproduction

The README included example snippets with a missing comma, an incorrect API class name, an incomplete catch(...) chain, and a malformed fenced code block terminator.

Analysis

The generated SDK exports ImagesApi, but one README example mixed ImageApi and ImagesApi. The same section also had an incomplete promise chain. Separately, the createProfile example had invalid object syntax as shown, and the organizational helpers example closed with four backticks.

Patch Summary

• fix the createProfile example syntax/indentation
• fix the organizational helpers fenced code block terminator
• change the image upload example to consistently use ImagesApi
• add the missing ); in the image upload catch(...) chain
• add a regression test for the corrected README examples

Risks

Low. The change is limited to documentation snippets and a lightweight README validation test.

Test Coverage

• added tests/check-readme-examples.js
• confirmed it fails before the README fix and passes after the fix
