fix(publisher): Fix endpoint security API key re-saving issue

Fixes an issue in the Publisher portal where the when the endpoint security API Key is saved without any changes, it was being re-saved and causing unnecessary updates. This commit ensures that the API Key in only gets updated when there are actual changes made to it, preventing redundant inconsistent updates.

Resolves: #4983
