UI Service Functions Spam Call Detection

We have added spam call detection to the UI service functions. When the same function is called with the same arguments 3 or more times within a 500ms window, a warning is logged to the browser console in non-production environments.

This feature helps identify unintentional repeated calls to UI service functions, which can be caused by component re-renders in client-side libraries (such as React, Angular, or Vue) or other common integration pitfalls. The warning includes the function name, the number of calls detected, the arguments passed, and a stack trace to help pinpoint the source of the issue.

The detection is observational only -- the function calls are still executed normally. No calls are blocked or deduplicated. The purpose is to surface potential performance issues and integration bugs early during development.
