Subject: [PATCH] Add test case for production endpoint removal on MCP Runtime
 page

Existing tests (00 and 01) only cover the sandbox endpoint deletion
  scenario. This adds the mirror case - deleting the production
  endpoint - to cover the other half of the optional-chaining fix
  mentioned in the original bug fix comments.
